The four standards of a successful man are one hundred and eighty centimeters, one hundred and eighty square meters, one hundred and eighty millimeters, and one hundred and eighty minutes.

Yunluo felt that she was more than capable. She was very capable, but she was still bullied by An Chuyu at home. Needless to say, her fiancée An Chuyu was the most important at home. If she asked Yunluo to change her dirty clothes, she would do it. If she asked Yunluo to have breakfast, she would eat it. If she asked Yunluo to coax An Qingju, she would do it.

An Chuyu happily went to the spacious bathroom to wash clothes for Yunluo, leaving Yunluo, An Qingjue and Tangtang in the bedroom. An Chuyu was relieved that her fiancé and her sister were alone together. After all, An Chuyu had done more extreme things, so she didn't think it was unacceptable for a man and a woman to be alone together.

Brother-in-law slept with Yunluo. An Chuyu was so bold that he could do such a thing. As long as An Qingjue and Yunluo were innocent, An Chuyu would pretend not to see the hugs and kisses. It can be said that An Chuyu should bear the greatest responsibility for An Qingjue's intimacy with Yunluo.

An Chuyu is a very wise girl, in order to give her pure body to her husband Yunluo on the wedding night, An Chuyu has to make sacrifices and take gains, so she asks her sister to sleep in the same bed with Yunluo, just to be safe, to ensure that Yunluo is not shameless enough to eat An Chuyu in front of her sister.

Facts have proved that An Chuyu's move was truly a stroke of genius, and it allowed An Chuyu to safely maintain his innocence.

But An Chuyu felt a little guilty towards An Qingjue. Besides, An Chuyu was probably not that confident about Yan Chenyu. An Qingjue was a card played by An Chuyu. Compared with An Qingjue, her best friend Yan Chenyu was a beautiful and cold beauty. She was also Yun Luo's classmate for many years. Logically, An Chuyu should be most wary of Yan Chenyu.

The reality is far more outrageous than imagined. Before Yan Chenyu lost her father in the third year of junior high school, she really had no other thoughts about Yun Luo. She even liked to play tricks on Yun Luo with An Chuyu. An Chuyu stared at Yan Chenyu for a year, but didn't notice anything wrong. So he stopped staring at her seriously.

In junior high school, high school, and college, Yan Chenyu and An Chuyu had already had a sisterly friendship, and neither of them wanted to hurt the other.

…

Yun Luo was definitely not a good person. How could a good person wash clothes in the bathroom when his fiancée was only ten meters away? He dared to hold his sister-in-law and sit on the edge of the solid wood bed. It was nonsense. He was so bold that the bedroom was half open.

But Yunluo did it openly, and An Qingjue didn't think there was anything wrong with it. Even if An Chuyu saw it, she wouldn't do anything to Yunluo. After years of getting along, childhood sweethearts are more than just four words. Yunluo, An Chuyu, An Qingjue, and Yan Chenyu already have a deep friendship and affection behind them.

The four of them grew up together, and the years went by slowly, with him and her.

An Qingjue was unhappy. Seeing Yunluo kissing An Chuyu passionately in front of her sister-in-law, An Chuyu felt a little shy. Especially in front of her sister, but An Chuyu was very generous. She was the one who took the initiative to ask for a kiss, so she would give Yunluo some space to make An Qingjue happy.

Of course, if Yun Luo dared to kiss An Qingjue, An Chuyu would make sure Yun Luo knew how a slapping sounded! It was a brother-in-law's duty to coax his sister-in-law, but kissing her was out of line. He really wanted to be beaten.

Yunluo held An Qingjue in his arms, and his sister-in-law rubbed against him, burying her head in his chest, but not looking at him. Yunluo breathed in the scent of lemon, the scent of his sister-in-law, and smiled slightly. He said softly, "Qingjue, my brother-in-law saw a very funny post a few days ago, and I'm telling you about it to make you happy."

"Hmph." An Qingjue snorted, not wanting to pay attention to this bad guy Yunluo, but her little ears perked up.

"Why did I end up on the road of learning Chinese, and then on the road of teaching Chinese as a foreign language? Every time someone asks me what I majored in, they are still confused after I tell them. So now after I finish teaching Chinese as a foreign language, I automatically explain that I am teaching Chinese to foreigners."

"When the other party hears the word 'laowai', their eyes light up and they immediately ask if your profession has good employment prospects and high incomes, and if you have many opportunities to study abroad, but you can only hum and ha ha, with a fake smile and a guilty conscience, you are so crazy about Chinese... so crazy about you."

"During the Spring Festival Gala, people only know how many Confucius Institutes have been opened around the world, how many Hope Primary Schools can be built by opening one Confucius Institute, and the National Office for Teaching Chinese as a Foreign Language only knows how to brag that tens of thousands of foreign friends are learning Chinese this year, and that many Confucius Institutes are free, especially in wealthy countries like the United States."

Yunluo has a strong sense of comedy. Whenever he wants to be funny, he can do it very smoothly. As soon as he opened his mouth, An Qingjue's beautiful eyes lit up, and a sweet smile appeared on her pretty face buried in her brother-in-law's sturdy chest.

"You can't even solve your own education problem and you're going to help the rich with education and poverty alleviation. If the Goethe Institute and the Cervantes Institute were free, you'd go there to study. There are so many opportunities to study abroad... so many opportunities, you want to go abroad with a bachelor's or master's degree? You can either work at a Chinese school or volunteer for a formal project."

"You can choose between one to three years, but whether you can stay abroad or find a good job after returning home is not something you can choose. You can't avoid being dragged from a young girl to a leftover woman. If you finish your doctorate and are lucky enough to stay in university, you can still go abroad."

"But then it won't be a matter of whether you want to go abroad or not, but you have to go abroad to train. After two years, when you have trained enough and return home, your husband will divorce you, right? When those people say we have good jobs and high salaries, they actually despise us in their hearts and say, who can't speak Chinese? I can teach you well even if I ask them to, right?"

An Qingjue likes to see Yunluo being serious about her, because it's for her alone, not for her sister An Chuyu or Yan Chenyu. In An Qingjue's heart, the most annoying classmate is probably Yunluo, who is really a thorn in the side. Yunluo is unaware of her sister-in-law's thoughts, and is still talking in a very emotional tone.

"I want to ask you, do you know the difference between for and to? Can you summarize the differences and similarities between happy, joyful, and cheerful? So many people are complaining about the physical and mental state of learning foreign languages. They say you have to memorize them, and it's over after you memorize them. It's really sinful for foreigners to learn Chinese."

"Nima ba sentences, nima complements, nima de complements, nima de modal complements, which foreign language has them? Which foreign language has them? Nima, every reference says that these things are unique to Chinese, and so far no foreign language has been found to have the corresponding sentence patterns. Nima, foreigners who learn Chinese are angels with broken wings."

"We are the ones who are trying to straighten out these crooked angels. What kind of amazing skills does this require? And the pronunciation, the pronunciation. The most difficult initial consonants I've ever taught are the post-tongue voiced fricatives, and the most difficult finals I've ever taught are the front-tongue high rounded vowels."

Little Tangtang was shaking her big, furry, bright red tail, showing that she had absolutely no interest in human words. She was playing with her cute little paws and counting her fingers, then her toes. Tangtang was having a lot of fun and was indifferent to the nonsense Yunluo was saying to the girl.

"When I teach you, you can't understand just by saying it. You have to perform while you're saying it. I finally get the pronunciation right, but it's all over when I start saying a sentence. Fuck you, you little witch doctor. And the intonation is so unique. The flat, rising, and entering intonations are annoying enough for foreigners, and then there are all kinds of intonation changes."

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

"Originally my last name is Lu and his last name is Mei, but the British and Americans say my last name is Lu and his last name is Mei. My last name is your sister, and there are kids studying international relations asking us, "Meiguo, Faguo, Hanguo, Deguo..." I finally got the words almost right, but when I tried to read the sentences, it was all over again."

"Just the words like good person and America with the third and second tones are enough to make me exhausted. The above are all obvious questions. I don't know how advanced those students are. The questions they ask are questions that you have never thought of, but they are very brain-consuming when you think about them carefully."

An Qingjue chuckled, which cheered up Yunluo. Knowing that this method was effective, Yunluo worked even harder and used his superb acting skills. He recalled that Yunluo had been witty and calm in French and English competitions, and had a variety of witty ideas. It was easy for him to coax a little girl.

"There was an international student who entered the classroom just as the bell rang. The teacher told him to come earlier next time. You almost got late today. Then the next day, the unlucky international student entered the classroom just as the bell rang again. The teacher told him to come earlier next time. You almost got late today."

"The student got angry right away. Why did you say two completely opposite sentences for the same situation? One was late and the other was not late. Such a big negative adverb was totally ignored. How do you explain this situation?"

"Of course, there are ways to explain it. According to functional linguistics, social psychology, and various studies... Are you sure the students can understand it? However, there are indeed many interesting things in teaching foreigners to speak Chinese. You will definitely hear hilarious Chinese words that you can't even think of during the teaching process."

Yunluo had sharp ears and could hear An Chuyu throwing all the big clothes into the washing machine in the bathroom. The small clothes that were close to the body had to be washed by hand. In this matter, An Chuyu was never lazy. When he had time, he would wash Yunluo's dirty clothes.

Since his fiancée hadn't come yet, Yunluo was justified in hugging his cute sister-in-law. He followed his fiancée's instructions and came to make his sister-in-law happy. He didn't do anything. It was a normal exchange, one talking and the other listening. It was so natural, except that Yunluo was hugging An Qingjue, which was abnormal.
