Song Hao turned the handle in the opposite direction, and the grain fell slowly and steadily to the ground.

Gu Fei found an axe, cut down the fence just marked by Mi Gang, and installed another wooden door that can be pushed open.

After doing this, they conducted another experiment, this time increasing the grain weight from 50 kg to 150 kg.

Song Hao had a little trouble turning his hand. Fortunately, he was strong enough and the house was built strong enough. Finally, the grain was hung on the second floor and fell back to the ground again.

Jiang Weiwei watched their operation all the way. He was again glad that when he built the house, he used all bluestone bricks, the beam was also a Bold version, and stone columns were added in the house. The house was extremely strong, otherwise it couldn't stand such trouble.

Then several tests were carried out.

The final results show that the maximum bearing weight of the pulley is 180 kg. If it is heavier, the rope will be a little stretched, and the wooden handle is in danger of being broken.

After confirming that there is no problem with the safety of the elevator, Xiaofeng pushes grandpa out of the ward in a wheelchair.

Song Hao and Mi Gang tied the rope to the armrest of the wheelchair.

They pulled off the rope to make sure it was strong enough, and then greeted Gu Fei downstairs.

"All right!"

Gu Fei slowly turned the handle.

Xiaofeng stared at Grandpa without blinking. When he saw grandpa descending with his wheelchair, he was very nervous for fear that Grandpa would have an accident.

Fortunately, nothing happened and the wheelchair landed on the ground smoothly.

Xiaofeng ran downstairs quickly and was very excited to see Grandpa safely in his wheelchair.

Old man Lou also thought it was very interesting. He asked curiously, "how did you think of it?"

Gu Fei said, "it's my daughter-in-law's way. With this elevator, it's much more convenient if you want to go downstairs in the future."

Old man Lou kept nodding and praising: "Dr. Jiang is really clever. He can come up with such a wonderful idea!"

Xiaofeng said crisply, "I will become a person like sister Wei in the future. I have ability and intelligence!"

Zhuang Zhuang happened to hear this. He didn't care about anything else. He quickly raised his little fat claw and shouted together.

"Me too. I want to be as capable as sister Wei and brother Xiaofeng!"

When they heard this, they all laughed.

Xiaofeng wanted to push grandpa out to relax. Jiang Weiwei told him to wait a minute. She took a blanket and covered the old man's leg. "It's still cold now. It's not easy to catch cold."

Xiaofeng nodded quickly and said thank you.

Old man Lou took a deep look at Jiang and his eyes were full of gratitude.

Because he knew in his heart that Dr. Jiang specially gave him a blanket to take care of his self-esteem. Now he has no legs below his knees. If he goes out and is seen, he must be pointed out. Now he covers his legs with a blanket, others don't know that he doesn't have legs, and naturally they won't say much.

This carefulness is really deeply moving.

Jiang slightly touched Xiaofeng's head: "go, be careful on the road, don't go too far."

"Yes!"

Xiaofeng pushed grandpa out of the door. They didn't go far, so they turned around in the yard. Today the weather is very good and sunny. Old Lou felt the sunshine he hadn't seen for a long time and was very happy.

Many patients waiting to see a doctor saw Xiaofeng and sun, and someone asked curiously.

"Where did you make this wheelchair? It looks very good. "

The man who asked this was a middle-aged man. He accompanied his father to see a doctor today. His father had problems with his legs and feet. When he was young, he could barely walk a few steps with a crutch. Now he can't even walk a step when he is old. He can only stay at home all day. He looks that he is not only thin, but also very poor in spirit.

Now his father is sitting next to him, his eyes fixed on the wheelchair.

Although his father didn't speak, anyone could see that he also wanted to go out in a wheelchair.

Seeing this, the middle-aged man took the initiative to ask about the wheelchair.

Xiaofeng said solemnly, "this wheelchair is rented by Dr. Jiang to us. If you want, you can ask Dr. Jiang."

"OK!"

At the right moment, ah Tao shouted to the middle-aged man. He hurried into the house with his father on his back.

Jiang Weiwei had the habit of writing medical records and asked, "what's the patient's name? how old are you? What's wrong? "

The middle-aged man truthfully replied, "my father's name is Zou Wei. He is 65 years old. He fell and hurt when he was young, leaving sequelae. He can't walk. Please show him."

Jiang Weiwei brushed down the beginning of the medical record, then got up and went to Zou Wei's father and examined him.

Zou Wenhui stood by and looked at them without blinking.

A moment later, Jiang straightened up slightly and said truthfully, "your father should have broken his leg bone when he was young. If he could be treated in time, he should be cured. Unfortunately, in the past so many years, we have long missed the best opportunity for treatment. I can help your father connect the leg bones now, but your father's muscles have been seriously atrophied. If you try to cooperate with the treatment in the future, it's OK to walk a few steps, but it's impossible to recover completely. See if you can accept it? I'll treat your father if I can accept it. "

Zou Wenhui hurriedly replied, "of course, it's better to take a few steps than not to take a step!"

Jiang nodded slightly, "well, carry your father to that house."

She pointed to the observation room next to her.

Zou Wenhui picked up his father and walked steadily into the observation room.

Jiang Wei put on his gloves and mask and began to set up a bone for Mr. Zou Wei.

The process of moving the broken bone back to its original position and reconnecting it is extremely painful.

Old man Zou Wei was sweating with pain and kept shouting pain.

Zou Wenhui was so distressed that he grabbed his father's hand and kept comforting his father.

After connecting the bones, Jiang Weiwei tied his legs firmly with splints and bandages and said to Zou Wenhui.

"Your father needs to stay in the hospital for two days. I'll give him acupuncture these two days. After two days, your father can be discharged from the hospital. Then you can take him home to take good care of him."

Zou Wenhui hurriedly agreed.

Jiang Weiwei called song Hao and Mi Gang over.

"You two take old Zou Wei to the second floor and find a hospital bed to settle down."

Song Hao and Mi Gang immediately carried Zou Wei out of the observation room with a stretcher, and then hung Zou Wei up the second floor with a hand-operated elevator.

Zou Wenhui was shocked to see this scene.

When Zou Wei was safely sent to the second floor, Zou Wenhui came back and exclaimed, "your method of transporting patients is too clever. How did you think of it?"

Song Hao smiled: "you have to ask our doctor Jiang. She came up with this method."
