Chapter 173 Pattern

"Aying!" Su Ying was about to enter the house when Su Laoer called her.

"Second uncle, haven't you rested yet?" Su Ying was very surprised. She was so sleepy, but her second uncle had something to do and was still waiting for her.

"Um, um..." Su Lao Er hesitated, "How's that Miss Wang Wu?"

"I injured my left calf. I've been taking medicine and I guess I'll have to stay in bed for a long time. It'll take a hundred days for the injury to heal." Su Ying replied while resisting the urge to sleep.

Su Lao Er was silent for a while, "Then who will take care of her? Her parents-in-law are old, she..."

"Stay at my mother's house. Oh, it looks like Wangcun is in trouble!"

Su Ying's mind was in a trance. She didn't want to think about these troubles. There were too many pitiful people in the world, and she couldn't sympathize with them all. "Second Uncle, take a break!"

"Hmm!" Su Laoer wanted to say something, but seeing that his niece was sleepy, he held back and didn't say anything.

When I entered the room, Mrs. Su had already fallen asleep, and Su Lu was also asleep hugging Atang.

Su Ying tiptoed in, still startling Atang, who opened his eyes and said, "Sister!"

"Be good and go to sleep!" Su Ying gently moved Atang's little head.

Several new quilts were added to the house. In addition to the thick straw, there was also a mattress under the bamboo bed, making it soft to sleep on.

Su Ying fell asleep in seconds, so sweet!

"Ding ding, bang bang!" As soon as I closed my eyes, the noisy sounds of dinging and clanging rang in my ears.

Su Ying turned over. Who is it that is still awake in the middle of the night?

The aroma of vegetable porridge penetrated Su Ying's nostrils. Her chaotic mind froze for a while before she came to her senses. It was dawn!

I sat up and saw that it was already bright outside. The people who came to build the house had started working.

The old lady, Su Lu and Atang in the room had already gotten up and did not disturb her.

I folded the quilt and opened the door. A gust of cold wind made me shiver unconsciously. Hiss, it's so cold!

It's not the ice and snow of Chang'an City. The damp cold here plus the mountain breeze creates another kind of cold. When the wind blows, it penetrates the front and back of the body, taking away the heat from the body, and making you feel completely cool.

"Aying, why don't you sleep a little longer?" Su Bucheng had just finished breakfast.

"There are so many things to do, how can I sleep!" Su Ying scooped a bucket of cold water to wash her face.

The shock of cold water instantly eliminated my sleepiness and I became refreshed.

"Don't you want to add some hot water?" Su Bucheng couldn't help laughing when he saw his daughter stamping her feet in shock at the cold water.

"Cold water to wake you up!" Su Ying finished washing up in a few seconds.

"Burp, burp!" The cries of piglets came from the pigpen, and they were smacking their food.

Mrs. Du and Mrs. Wei came back carrying empty buckets. The piglets had grown a lot and their appetite had increased, so it was too difficult for one person to carry the pig feed.

The old lady brought some grass to feed the cows. The cowshed was next to the pigpen. The cows would occasionally moo, but were usually very quiet.

Su Ying held the bowl and drank porridge, watching her father and second uncle leave. Her second uncle looked at her hesitantly, as if he wanted to say something.

Su Laoer's cotton coat was torn in many places yesterday, revealing the kapok fibers.

After days of blasting rocks, he was covered in dust and dirt, a bit like a beggar, which was inexplicably funny.

Su Ying smiled at her second uncle and finished the porridge in a few mouthfuls.

The residential and school buildings have taken shape, the foundations have been laid, dozens of pillars are standing, the beams have been reinforced, and the frames have been erected.

The next step is to build the walls with bamboo fences, apply mortar made of a mixture of yellow mud, clay, and straw, put up the beams, and cover it with thatch, and the new house is done!

The construction site is busy but not chaotic, and everything is well organized.

"Uncle Wang Sanlang!" When Su Ying saw Wang Sanlang, she inexplicably thought of her second uncle's hesitation to speak.

"What's the matter? Aying!" Wang Sanlang came over.

"I'd like to trouble you to make something. Are you free?" Su Ying asked.

"What is it? Ah Ying asked me to do it, so I must have time for it!" Wang Sanlang smiled.

"Can you make a wheelchair? The kind that Prime Minister Zhuge Liang used during the Three Kingdoms period, which can be pushed or the wheels can be turned by itself to move." Su Ying suddenly understood what her second uncle wanted to say.

"Prime Minister Zhuge's wheelchair?" Wang Sanlang was stunned and scratched his head. He had heard of it but never seen it.

He used to be a playboy who knew how to eat, drink and have fun. He had some knowledge, but not much.

I fall asleep as soon as I read historical books like "Records of the Grand Historian", "Book of Han" and "Records of the Three Kingdoms". How can I pay attention to any insignificant detail in them?

"Come on, I'll draw one and you can see if you can make it!" Su Ying pulled Wang Sanlang to the blackboard.

The children who were about to attend class were curious and watched Su Ying draw quietly.

One has a seat, armrests and a backrest on the seat, and handles on the backrest; the rear wheels are large, the front wheels are small, and there are foot pedals.

"Wow! What is this?" The children saw another new thing.

"Wheelchair!" Su Ying looked at Wang Sanlang, "Can this be made?"

"Yes, it is possible, but it will take some time. The wheels are not easy to make." Wang Sanlang considered.

It is all fixed by mortise and tenon joints. The wheels need to bend the wood and then fit together tightly. It is a test of carpentry skills, especially the two small wheels.

If Lord Lu had not taken over the development of the foot-operated thresher, Wang Sanlang would not have had the energy to build school buildings and residences.

"Is this urgent?" Wang Sanlang asked. "Right now, the school and housing are at a critical juncture. We can't afford to be distracted."

"It's neither urgent nor bad. It's for Yang's elder sister. She broke her leg and has difficulty moving. With this wheelchair, she can move freely." Su Ying explained.

Wang Sanlang didn't expect it to be related to their Wang family. "Thank you, Aying!"

"What are you thanking me for? We're from the same village. It's not too late to do this when you have time. How about this one?" Su Ying drew another pair of crutch.

"This is easy!" Wang Sanlang looked at it and nodded. "I can make it the day after tomorrow. What is it called? It's also for Wulang's wife."

"A crutch. Sister Yang has difficulty walking, so she can walk with it." Su Ying said.

"This is quite clever. It's simpler and more practical than a wheelchair," Wang Sanlang commented.

"This is a score. Miss Yang is young and her leg injury can be recovered. The crutch is light and simple to make, so it is relatively useful.

However, for patients with irreversible leg diseases or elderly people who are unable to walk due to physical weakness, a wheelchair is the best aid.

Moreover, a groove can be opened on the seat of the wheelchair to make a movable drawer. If there is an emergency, the movable seat can be pulled out and a toilet can be placed underneath to solve the problem, avoiding the embarrassment and trouble of having to stay in bed.

"Hey, Aying, what you said makes a lot of sense!" There were many villagers present, and which family didn't have elderly people?

"Think about this slowly when you have time. You can make a few and sell them to Shopkeeper Zhu later. Maybe you can even sell them to other places." Su Ying's words went off topic.

"Okay, class starts, class starts!" Su Ying was about to erase the picture on the blackboard.

"Aying, don't wipe it, let's take a look again!" The children's cognition was shocked.

They were amazed by the wheelchair as they read the books of sages in a serious manner. They never expected that a slight improvement in the seat could solve the three urgent needs of people with mobility impairments.

This cognition changed their rigid book-learning mindset and made them realize that the real use of knowledge is to change the environment, boost productivity and promote development.

It is not just for the purpose of imperial examinations, promotion or wealth.

Once the cognition changes, people will be motivated to learn and their vision will become broader. It is no longer about narrow family glory, but about becoming a person who is useful to society and leaving a name in history.
