"This..." The couple looked at each other in disbelief.

Anyone could see that they were not welcome, and the words spoken were not polite at all.

Li Xiuxiu wanted to ask something else, but the baby in her husband Zhao Quan's arms suddenly opened his mouth and burst into tears.

The child wanted to drink milk. This was her baby bump. Li Xiuxiu stood up without thinking and said, "See you next time. I'm going home with my husband first."

"Where are you going back to, the countryside or...?" Aunt Chen asked with a frown.

"We're not going back to the countryside. We're living in the city now." He patted his two daughters on the shoulders and said, "Come on, Chunni and Xiani, say goodbye to your uncles and aunts."

The two children's lips were trembling from the cold, and they couldn't even talk or walk steadily. However, they didn't dare to disobey their mother. They opened their purple lips and said tremblingly: "Uncle, auntie, bye, bye..."

After saying that, Li Xiuxiu hurriedly led her family away.

"That's it? Does Li Xiuxiu really have a place to live? Did she really come back just to see her dad?" Chen Jiamei stared at the backs of the family of five as they left, muttering in disbelief.

Upon seeing this, Aunt Chen suddenly chased after him.

"Xiu Xiu! Xiu Xiu!" He took three breaths with each step and finally caught up with them.

Li Xiuxiu stopped and turned her head. Before she could see who was coming, two Mao bills were stuffed into her hand.

"Here, buy some food for the two children. Look how hungry they are!" Two dollars can't buy clothes, but you can buy some hot meals. Filling your stomach can at least keep your body warm.

Li Xiuxiu grew up under the care of Aunt Chen. Their family had a good relationship with the Li family, and she was treated like her own daughter since she was young.

As for Li Xiuxiu, she was actually quite lively and cute when she was a child. Although she became ungrateful when she grew up, the two girls around her were innocent anyway.

The daughters look like their mother. When Aunt Chen saw them, she seemed to see Li Xiuxiu's childhood. She was overwhelmed with emotion and couldn't help but take out the two pieces of money.

"Thank you." Unable to describe the feeling in her heart, Li Xiuxiu hugged her gratefully.

He turned around, walked on the bluestone slabs step by step, and left the compound.

I looked at the backs of the family of five walking further and further away and sighed.

After returning home, the neighbors enthusiastically discussed Li Xiuxiu's story.

"Where do they live?"

"have no idea."

"It doesn't matter where they live, even if they live in a cave!"

"Those two kids are Li Xiuxiu's daughters, right? They are so dirty, yet they clean themselves up so cleanly... They favor boys over girls? Bah! So immoral!" What Chen Jiamei hates most is favoring boys over girls.

She herself is a lesbian. Although she has three older brothers, fortunately her parents are not partial to one of them. Otherwise, her fate would probably be the same as those two little girls, so shameful!

Song Qingping snorted disdainfully: "Why would you come here with your family? You must want to settle down here. If you're quiet now, I guess you don't know that the house has been taken away by Xu Haizhou, and you're going back to think of a solution!"

After all was said and done, Song Qingping's statement was the most reliable, and everyone nodded in agreement.

"If her father wasn't dead, he would probably be so angry that he would die if he saw her."

"Oh, stop talking and go home to eat."

…

Of course, Li Xiuxiu's family of five couldn't find a place to live, and even the train tickets were funded by relatives, friends and the team leader... She promised to send the money back when she met her father.

Who knew that her father had died and the house had changed hands? Li Xiuxiu really didn't know what to do for a moment.

In addition, all the neighbors blamed her and she was outnumbered. Li Xiuxiu didn't dare to break up with Xu Haizhou now. After that, she would have no chance to say anything. She had better retreat now and think of a solution later.

They had no money to go to a guesthouse, and couldn't find a suitable place to sleep, so the family of five could only spend the night in an empty old temple.

No one had come to the old temple for a long time, and the thick dust made it hard for the two little girls to breathe. Then they looked at the baby in Zhao Quan's arms, whose head was lightly covered by the quilt, so the dust could not fall on his face.

"What should we do with the house? It's your Li family's house. Are we just going to give it to that kid?" Zhao Quan cleared out a small clean area in annoyance.

"You don't know." Li Xiuxiu rubbed her hair irritably. Her son sucked breast milk in big mouthfuls. She grimaced in pain for a long time before she had the strength to speak: "After I had a quarrel with my father because of you, I asked Xu Haizhou to take care of him. But I didn't expect that the old man could be mad at me. Didn't you hear them say that it was Xu Haizhou who took care of my father that made the old man confused and gave the house to him."

"Your father doesn't know that you are still alive. He must have thought you were dead, so..." Zhao Quan said.

"No matter what the reason, the house is now Xu Haizhou's legal property. We will get nothing if we go and make trouble." Although Li Xiuxiu has lived in the countryside for more than a decade, she was a real junior high school graduate before going to the countryside.

If she hadn't gone to the countryside, she would have been admitted to a technical school.

Therefore, she is not a brainless woman, but she has a low IQ when it comes to love and family affection.

Now that she has analyzed it with her husband, the rules are quite clear.

"What should I do? I don't want the house anymore?" How much would two big rooms be worth in a city as big as Li'an?

Zhao Quan suddenly felt very regretful, very regretful, extremely regretful!

If I had listened to Li Shunliang and stayed in the city, what would the situation be like now?

Xu Haizhou came to my mind unconsciously. He was dressed so well and had a bicycle. I just stood at the door and looked into the house. There was a TV and a radio. Everything!

If they had stayed in the city, would everything in the house have become his and Li Xiuxiu's property?

The more I think about it, the more unwilling I feel.

All of that should have belonged to him and Xiuxiu, how could it be taken away by an outsider like Xu Haizhou? !

In fact, he should blame his parents. If the old couple were not narrow-minded and felt that a man should not live with a woman, he would not have strongly demanded that Li Xiuxiu settle down in the countryside.

When his parents passed away, Zhao Quan suddenly realized that he seemed to have made a very wrong decision.

"Yes, of course. That's my dad's house." After eating and drinking his fill, the son in her arms fell into a deep sleep again.

Li Xiuxiu gritted her teeth, handed her son to Zhao Quan, and took a deep breath: "When the time comes, we will sell him badly and act pitiful... You just saw it, the Chen family's aunts are soft-hearted and pity our two girls. If we act more pitiful in the future, will Xu Haizhou and his wife..."

Zhao Quan immediately denied her idea: "No, the old woman only gave you two yuan. No matter how pitiful she is, can she still vacate her house for us to live in? Besides, it's not her who decides on your Li family's house. Now it belongs to Xu Haizhou. That man is obviously not a soft-hearted person. Do you expect him to be soft-hearted?"

Li Xiuxiu shook her head: "Xu Haizhou is a kind person, otherwise he wouldn't have saved my family and wouldn't have agreed to take care of my dad... You don't know him, I think it's possible."

"Those are two houses! Houses in the city! No matter how kind a person is, would he vacate his houses and give them to you? Do you think he is stupid?" Women cannot imagine how realistic men are.

On this point, Zhao Quan has the most say.

Li Xiuxiu is simple, but he is not simple.

Except for the fact that he initially did not agree to stay in the city with her, Zhao Quan was better than Li Xiuxiu in many real-life matters.

If Li Xiuxiu was smart, would she be willing to stay in the countryside and live a hard life with him?

Thinking about it now, he felt that Li Xiuxiu was simply hopelessly stupid!

"I say you are too soft-hearted!" Zhao Quan's education is not as high as Li Xiuxiu's. He only graduated from elementary school. When he was angry, he could even blurt out a few idioms. It's really like a knife pulling the butt. He is really open-minded.

Li Xiuxiu was already in a bad mood, and now she was scolded by Zhao Quan, so she became angry.

Turning his back, he said angrily, "I don't have the face to ask for it anyway, so if you want, go by yourself."

Zhao Quan's dark eyebrows knitted deeply: "You have no shame, but I have? You want me to claim your own house?"

"No, why can't you go? You are the head of the family, my Li Xiuxiu's man, and the son-in-law of our Li family. What's wrong with you going? You are not an outsider, why can't I go?" Li Xiuxiu held her chest and took a breath: "Besides, if it wasn't for you, would I be reluctant to buy a train ticket or even write a letter? I am wholeheartedly with you, are you blaming me now? What do you mean?"

Poor couples have many worries, and this saying perfectly illustrates Li Xiuxiu's marriage.

It was true love when they were together at first, and they were truly attracted to each other, but in the end they were crushed by the mountain of reality.

Li Xiuxiu is a stubborn person. Once she makes up her mind about something, even eight oxen can't pull her back.

It was when I first went to the countryside, when I got married, and finally when I gave up city life and decided to take root in the countryside.

Likewise, people who are so impulsive are more likely to regret if their lives are not as they wish.

Looking at her shivering daughter beside her, and then at her sleeping son in the cradle... Li Xiuxiu closed her eyes, and the experiences of the past decade or so flashed before her eyes like a rewind.

Vividly in my mind.

How did it become the current situation?

The two children listened to their parents quarreling, not daring to breathe. Because it was cold, they huddled together with a pile of bundles to keep warm.

All they hope for now is a warm house. As for food, it's okay to go hungry for a few meals.

They had been cold for too long as they had been bumpy all the way from Damao Village to Li'an, stopping and starting frequently.

After arguing for a while without any result, Zhao Quan snorted unhappily, gathered his coat, and lay down with his son in his arms:

"Forget about it. Let's go to sleep first. We'll deal with it tonight and then think of a solution. After all, the house was given to him by your father. If he has sense, he should return the house to us."

"What if he doesn't return it?" Li Xiuxiu asked in despair.

"You won't return it? If you don't return it, at least you have to give me a room to live in, or I'll..."

Zhao Quan is a very patriarchal man and is very concerned about his reputation. If he had been a little thicker-skinned, he would have asked Xu Haizhou to return the house just now.

Isn't it because there are so many people around that you don't dare to speak?

Li Xiuxiu looked at him mockingly: "What do you think? Do you think this is your countryside and you can just give it a beating?"

Zhao Quan was speechless and curled his lips: "Anyway, we can't let him have an easy time. The house was originally yours."

…

The neighbors in the large compound all thought that Li Xiuxiu came back to Li'an with her family to take the house back.

As a result, everything was peaceful for half a month and nothing happened.

Here in the inner courtyard, Qiaoan has learned how to use the rice cooker under Qiao Lu's instruction.

The boy jumped up excitedly and hugged Qiao Lu: "Mom, the rice cooker is amazing! I will be able to cook for myself in the future!"

Qiao Lu teased him: "When your parents are not at home, you won't be hungry anymore, right?"

Qiao An actually nodded and said firmly: "Yes! Because I can cook by myself!"

"But you can't cook, so what about eating rice?" Qiao Lu tickled his chin amusedly.

"I just eat. I only eat. Even dry rice can fill my stomach."

Qiao An: I just eat dry rice!

Puff——

Children nowadays are really easy to raise. They won’t become skinny as long as they eat evenly from their parents’ mouths.

Thinking of Li Xiuxiu's two timid and thin daughters, Qiao Lu sighed.

If Qiao Lu hadn't traveled through time, the two girls would have ended up like Qiao An. But Qiao An was better off. At least, he was a boy and had grandparents who loved him at home...

It's really sad.

"Mom, tell me a story. I will go to sleep after listening to the story."

At night, while Xu Haizhou was taking a shower in the bathroom, the son usurped the throne and climbed onto the bed of Qiao Lu and her husband.

"Haven't you heard enough in kindergarten during the day?" Qiao Lu held her son in her arms, kneaded his little face, and said teasingly.

Qiaoan shook her head and leaned over softly, her body soft and limp: "The teacher only taught us to sing today, not tell us stories."

"You can recognize some words now, right? There are books in kindergarten, so why don't you read them yourself?"

The young man puffed out his chest proudly: "I have already finished reading all the kindergarten books."

Qiao Lu was surprised: "Is this true? You are so amazing. Have you read all of them?"

"Well, there are thirty children in our class and fifteen books. I can finish them in no time." Is it difficult to read fifteen books? One book a day, and I can finish them in half a month.

"Do you recognize all the words in it?" Qiao Lu asked again.

Qiao An shook his head: "I know some of them, but I don't know some of them. But I can ask the teacher!"

Then she said with a smile: "Teacher Qi is so nice. Every time I ask her, she will tell me and she won't call me stupid."

Fool?

"Have other teachers ever called you an idiot?" Qiao Lu frowned slightly.

Qiao An recalled carefully and pursed his lips:

"Well... once in that kindergarten, the teacher called me stupid. I forgot what it was, but after that, I didn't dare to look for her anymore."

That kindergarten? I guess he meant the kindergarten in the silk reeling factory.

Jolu rubbed the child's head with concern and sighed, "It's okay, it's all over. Mommy will tell you the story of the three little pigs today. Have you heard it?"

"Mom, I haven't heard of it yet."

The story was short, told at a leisurely pace of one minute, and halfway through it, Joan reached her climax.

"They had worked so hard to build this house, but the Big Bad Wolf was so bad! How could he be so bad? Mom, is that house still good?"

"Well, I haven't finished yet, please listen to me continue."

After finishing his speech, Qiao An still looked depressed:

"If, if the pig's parents were here, they wouldn't have to be afraid of the big bad wolf, and the big bad wolf wouldn't dare to bully them... The little pig is so pitiful——"

As he was talking, he actually felt a little depressed, and his little mouth drooped sadly.

Qiao Lu held his head with amusement and helplessness and kissed him: "Oh my son, why are you so immersed in the play? This is just a story, there is no need to think divergently."

It’s not good for your son to be too sensitive. He will easily put himself in other people’s stories and become overly emotional.

The little guy shook his head, looking like he was about to cry: "But, but the little pigs are so pitiful. They worked so hard to build the house, and then the big bad wolf destroyed it. The big bad wolf is so bad!"

"Yes, the Big Bad Wolf is a bit bad. Can Mommy tell you another story?"

"Um……"

Qiao Lu quickly told another heartwarming story, but the subject matter seemed to be poorly chosen, and the effect was not ideal?

"The Tadpole Looking for Its Mother", Qiao Lu originally thought this should be a very heartwarming story, but her son became depressed after listening to it.

Well, it seems that today is not the right day to tell stories.

He hugged her and whimpered, "Fortunately, my mother is always here, so I don't have to look for her. If my mother wasn't here, I would be so sad."

"Alright, alright, go to sleep and don't think about those things."

"Mom, can I sleep with you today?" He raised his index finger and made a small request.

Qiao Lu: "...So you became depressed today just to sleep with me?"

Finally, after taking a shower, Xu Haizhou returned home and saw his son occupying the seat that should have belonged to him on the big bed. He was dumbfounded...

…

"Jolu, are you ready?"

"Okay, okay, put on some lipstick!" My lips are so pale today that I'll look sick if I don't put on some red.

Since her son started kindergarten, Qiao Lu has to get up early every morning to send him to school.

In order to satisfy her son's "vanity", she has to put on beautiful makeup and wear beautiful clothes!

Alas, the old mother has really paid too much for her son!

"Why did the weather suddenly get cold? There's not even any sign of improvement." Pulling her coat together, Qiao Lu looked at the sky in wonder.

Xu Haizhou stepped forward, put his arm around her shoulders, and walked out of the yard pushing the bicycle with one hand.

"It looks like we need to prepare winter clothes."

"Well, let's see how things go next month. The last fall collection hasn't sold out yet. I think the sales are strong and the stock is almost sold out."

As soon as the couple pushed their bicycles to the outer yard, they ran into Xiao Zhou and Xiao Gao.

One month after their marriage, the two newlyweds seem to be in great spirits, and one can tell at a glance that they haven't been bothered by hooligans recently.

It’s quite funny to say, Qiao Lu also heard it from others.

It seemed like the thugs from a while ago came to his door, and Xiao Gao decided not to endure it anymore. He picked up a kitchen knife and fought them to the death.

He even turned around and told his wife a will: "If I die, you must remarry!"

Then, he picked up the kitchen knife and rushed out.

Seeing that he was totally ready to die, the gangster got really scared and ran away.

Nonsense, they haven't lived long enough! Desperadoes cannot be bullied!

"Sister Qiaolu! The clothes over there are finished, I'm here to pick them up!"

In addition to being happy about the gangster being chased away, she was even happier because she could make money by doing handicrafts with Gao Xin every day.

Although the couple did not have a sewing machine, they were diligent and willing to endure hardships. They worked day and night and could make at least three or four yuan a day, and they ensured the quality and quantity.

The money earned is more than enough to cover living expenses and even support two elderly people in the family!

Not to mention this young couple, even many factory workers and people with jobs now come to Qiao Lu's house to get goods for handicrafts.

As for money, who would complain about having too much?

This is the only thing Qiao Lu is thankful for, that she did not cooperate with the pirated manufacturer Qian.

As long as her small workshop is still in existence, people like Xiao Zhou and Xiao Gao can have a job to make a living.

"You go in and look for Wu Guifang. I'll take my son to school first."

"Oh, that's fine. Sister Qiao Lu, take care!"

Who among those who work part-time as a deliveryman at Qiaolu's house doesn't respect and like Qiaolu?

The one who gave the money was the boss, and Qiao Lu immediately became the most popular person in Ziyuan Street.

…

After sending her son to kindergarten, on the way home, Qiao Lu talked to Xu Haizhou about Li Xiuxiu.

"Haizhou, do you know where Li Xiuxiu's family lives now?"

"I don't know. I don't have time to pay attention to her when I'm busy with business every day." Instead of paying attention to their family, it is better to pay attention to what is missing from the new house and prepare them in advance.

"Haizhou, when I went to buy groceries yesterday, I passed by the Tudi Temple. You know that temple, right? It's at the intersection of Guixi Road and Yuannan Road. It's a dilapidated temple that has been abandoned for a long time. This family...seems to be living inside."

The temple has been abandoned for a long time. I heard that it will be demolished and a building will be built. It will probably take two months.

After the old temple was demolished, what would happen to the family of five?

And if they were discovered, they would definitely be chased away.

Xu Haizhou was obviously stunned for a moment, and then he turned his bike slowly into Ziyuan Street. His tone suddenly became calm: "What do you want to say? Take them to our house?"

"No, no." Qiao Lu shook her head repeatedly: "I'm not that saintly, mainly..."

Sighing, she said: "It's mainly because her two girls are so pitiful. You said Uncle Li's house..."

"The house is mine now, so there's no point in her making a fuss." It's hard to guess what Qiao Lu is thinking. She's mainly afraid that Li Xiuxiu is morally blackmailing him and that he will give the house back without consulting her.

But Xu Haizhou made it clear today that he would not return the house to her, at least not for free.

"Well, it seems you are not someone who can be easily manipulated." Qiao Lu hugged his waist tightly, put her face close to him, and said softly: "You saw her two daughters that day, how pitiful they were, skinny, timid, and their lips were frozen purple."

"It's useless to see them. Do you want to help them?"

Perhaps because she had raised a son, Qiao Lu always felt compassion when she saw the poor child.

"Not entirely, I just feel sorry for the child." She really has no sympathy for the adults, but the child is innocent...

"What do you think?" I simply asked him back.

"It's quite pitiful." However, there must be something hateful about a pitiful person. There are so many pitiful people in the world. It's just Li Xiuxiu's choice.

If he helps them just because they are pitiful, then there are so many pitiful people in the world, does he have to help them all?

"In fact, I originally thought that if Li Xiuxiu had been throwing a tantrum and asking us to return the house, we would not have returned it without trying to save face. But now half a month has passed, and this family of five has not come to make trouble once. They live peacefully in the dilapidated temple, so I began to feel some sympathy for them."

"Um."

"How about this, if they behave themselves and don't make trouble, we can rent Uncle Li's old house to them at a lower price after we move into our new home."

Xu Haizhou was silent for a while.

In fact, Xu Haizhou has always been resentful of Li Xiuxiu. When Li Shunliang died, he remembered the unwillingness in his eyes and his last words.

He said, "Haizhou, you are the only one left... After I die, I will bless you with peace and happiness in heaven. Xiuxiu, just think of her as going to find her mother. You should be well, be well..."

But the tears in the corners of his eyes clearly showed that he still couldn't let go of Li Xiuxiu.

That ungrateful daughter became his obsession until her death.

"Well, it's up to you. We won't be coming back to live here after we move out anyway."

If doing so could make her feel more at ease, Xu Haizhou didn't mind.

…

When I went to pick up my child in the afternoon, there was a lot of commotion at the kindergarten gate, as if something big had happened. Qiao Lu and her husband were in a hurry to pick up their child and didn't have time to join in the fun.

It was not until the next day, when I sent my son to kindergarten, that I heard the parents discussing it at the door.

It is said that a couple's little daughter on Qiu Shui Street went missing yesterday. She disappeared during the time when she was out of kindergarten!

The parents called the police, but a day and a night passed and no one was found. They cried their eyes out, but there was still no news at all.

He is such a young child, just in the kindergarten class, where can he go by himself?

At first, everyone didn't take it too seriously. They just sighed and warned their children not to run around.

Within two days, another child went missing, but this time he was from the next street, and he didn’t go missing in kindergarten either. Instead, he was lost while playing at the doorstep of his home.

Again, I called the police for a day but got nothing.

"Oh, could it be that he was kidnapped by a trafficker?"

One was an accident, but two? Isn't that just a coincidence?

"An An, the streets are not peaceful recently, just play in the yard." The news spread quickly, and parents were all worried. The kindergarten also strengthened its security. Unless parents and grandparents came to pick up the children, it would be difficult to prevent them from escaping from the school gate.

"Okay, Mom, I won't run around."

Later, Chen Jingkang and his friends came to ask him to go out and play, but he refused to go: "Mom said it's not safe outside recently, so I'll be good and play at home."

The children said angrily, "Okay, then we'll go by ourselves."

As soon as he walked out of the inner courtyard, he was stopped by Song Qingping's roar: "Chen Baitao! Where are you fooling around again! I wonder if you lost your child recently? You are not allowed to go out to play!"

"Then when can we go out?" The children came back dejectedly.

Song Qingping pulled her son's hand into the house and said, "I don't know. Let's talk about it in a few days. Come home and play!"

For a time, the disappearance of the two children caused panic among the people.

Five days later, the missing children were still not found. But since no more children were missing, the parents gradually relaxed.

Today, Qiao Lu and Xu Haizhou went to Baiyun Street together to discuss the issue of new products for winter. They went to the kindergarten to pick up their children around 4:30 in the afternoon, and were about ten minutes late.

Actually, it’s okay to be late. Nowadays, even if the parents are not there, the kindergarten teachers will not let the children go out.

At this point, Qiaoan was dazzled for some reason today and saw a familiar figure at the kindergarten gate. She stood up excitedly and said to the teacher, "Teacher! I saw my dad!"

So, I put on my schoolbag and ran out of the kindergarten quickly.

When I ran up to the person, I realized I had recognized the wrong person.

Not my dad, just an uncle who looks and dresses a bit like him!

The young guy walked back disappointed.

…

"Teacher Qi, where is our An An?" In the past, the little boy always sat on the first small bench waiting for them, but why was there no one there today?

Teacher Qi was busy handing other children over to their parents. After hearing this, he worked for two minutes before turning around and looking around: "I just saw him sitting here. He seemed to say he saw his father, and then he ran out."

"Dad?" Qiao Lu turned her head and looked at Xu Haizhou: "Isn't his dad here?"

Teacher Qi was at a loss. She searched the entire kindergarten but couldn't find any trace of Qiaoan.

This reminds me of two recent cases of missing children.

“Oh no!”

The couple went to the police station to report the case in a panic. The police officer looked helpless and said, "There have been many cases of children going missing recently. We are also actively searching for the traffickers. Let's leave a note and wait for news when we return."

The child is lost, there is no time to wait, go out and look for him!

But Lian is such a big city, trying to find little Qiao An is like looking for a needle in a haystack!

She walked until dark, and Qiao Lu's heart was already chilled.

Not only was she anxious, Xu Haizhou was also anxious, and the neighbors in the entire compound were anxious with them. Everyone split up and searched for two hours, but still found nothing.

I had no choice but to comfort the child's mother:

"Don't worry. Your child was lost this afternoon. The police cordoned off the railway station and bus station three days ago. They are conducting a strict investigation. He shouldn't have gotten far. He may still be in the city."

"No matter how far he runs, I just hope that An'an is safe and sound. Please don't hurt him, please don't..."

Before traveling through time, Qiao Lu had learned that abducted children might be sold into mountain ravines.

The obedient boys were made to do hard labor, or raised as sons to look after the old man when they grew up. The disobedient ones had their limbs broken and were forced to beg, in short, they were tortured in every possible way.

Girls are even simpler. They are abducted as child brides, or raised and sold to poor men in the mountains who cannot find wives.

When Qiao Lu thought about the series of experiences her lovely and well-behaved son would go through, her eyes went dark and she fainted.

The author has something to say:

I added more chapters today, two chapters in one

The house will not be rented out nor given away for free. The specific disposal will be explained in the next two chapters.
