After Dr. Qu came to see it, he also said that Lin Yu was a cold. In fact, looking at Yan zhòng, drink more hot water, cover sweating, and don't take the medicine.

Jing Hao was relieved at this time, but he still took care of Lin Yu carefully, and lived in this forest house for three days, and saw that Lin Yu was indeed alive, so he was relieved that Lin Yu went out.

When Lin Yu came out, he went to the shoe factory first, and asked them to make the backpack first, which should be about the same.

"Miss Lin's body is refreshing?" Seeing that Lin Yu was coming, Yang Yi hurriedly came out to say hello, after all, Lin Yu's illness was also a big deal in the Lin Mansion, and the big guys had heard about it when they were eating in the cafeteria.

"It's nothing, it's just that the wind and cold occasionally make the big guy toss." Lin Yu said with a smile.

"This should be Young Master Jing." Yang Yi smiled and greeted Jing Hao.

Jing Hao nodded, his eyes full of curiosity about the one in the room.

"I'm here to see how Master Niu's bag is made, and I want to see if the finished product is the same as I imagined." Lin Yudao.

"I made it yesterday, and I muttered several times that you couldn't come back yet, and I wanted you to help see what else was wrong." Speaking of Master Niu, Yang Yi was a little helpless. is old, but he really can't help but admire this enterprising spirit.

After speaking, he took Lin Yu and the two to Master Niu's house.

Master Niu was originally with all the workers, but later for the convenience of research, he got himself an office, which happened to move in the day before yesterday.

I saw that this house is not big, only about ten square meters. On both sides are shelves with various fabrics, needles and threads, and in the middle is a large desk with some scissors, measuring tapes and other utensils still placed on it. Behind is a small kang. There were a lot of bits and pieces of fabric on the kang, and there was also a shoe repair machine.

Seeing Lin Yu and the others coming in, Master Niu's eyes lit up, and he hurriedly swept away the cloth crumbs on his body and got down from the kang. Then he took out two thick cloth bags from under the desk, which was quite the feeling that Lin Yu said.

Lin Yu picked up the backpack and opened it to take a look. Sure enough, the inside is a drawstring design, and the knot is untied, and there is plenty of space inside.

Lin Yu tied the strap again. took off his cloak for Jing Hao to hold, and he carried his backpack.

The size of this backpack is okay, but this strap is a bit long. Probably Master Niu designed it according to his own figure, carrying it on Lin Yu's back. It's a little incongruous.

Lin Yu tried to stuff something inside. I put it on my back again, and I tried to memorize it for a while before taking it off.

"How did Master Niu feel after doing it?" Lin Yu asked.

"I didn't feel anything when I was carrying it, but looking at Miss Lin's back, I felt that the strap on this shoulder was a little long. But each person's height is different, can this strap be divided into a size like a shoe? Master Niu thought that his craftsmanship was okay, but it was only after being carried by Lin Yu that he saw such a shortcoming.

"It doesn't have to be that much trouble." Lin Yu smiled. "Have you seen the buckle on the saddle? Two iron rings next to each other, and shoved the strips of cloth into them. It was fixed immediately, and the length could be adjusted. ”

"Oh!" Master Niu suddenly understood, "You mean, turn this bag into an adjustable size?" Wonderful! This way, no matter how tall people are, they can use it! In the same way, this shoulder bag can be designed in the same way! After Lin Yu was on demand, Master Niu's face immediately burst into laughter.

Lin Yu casually picked up a piece of chalk with Master Niu drawing lines and drew a semicircle on a piece of cloth.

"We can make such an iron buckle. Just use thick iron wire to make such a semicircular shape. When the time comes, sew the two semicircles in this position of the bag," Lin Yu compared the middle and lower part of the bag strap with his hand, "Then let's make the lower half longer, and then stuff the lower strip of cloth into the iron buckle." Then the strap on it should be relatively short," said Lin Yu, who picked up the bag again, pulled the bag, dragged it to his appropriate height, and drew a white strip on the belt with chalk, "I am considered medium among women in height, so I can do it according to my height." Sew the buckle into this position. Then the shorter ones than me can tighten the straps underneath a bit. If you're taller than me, you can make the strap longer so that everyone can use it. ”

"That's a good way!" Yang Yi also understood, "I didn't expect to be able to use the buttons on the saddle on this backpack, Miss Lin touches the bypass, which is really admirable!" ”

This is Lin Yu's bypass, it's just that I have seen it a lot in modern times.

Lin Yu smiled embarrassedly and said, "Also, when I just stuffed something into it and carried it, I found a shortcoming. ”

"Oh?" Master Niu's eyes widened, why didn't he find out?

"Even if the back is a little heavier, the shoulders will be strangled. We don't move in the house, it's bearable. What would happen if you carried it on your back for half a day? ”

"However, when ordinary people endorse the book basket and bamboo basket, they will also panic." Yang Yi said.

"But usually if you have a backpack, it's not easy to carry it. Why is that? Lin Yu asked with a smile.

"Because the strap of the baggage is wide!" Master Niu blurted out. "Ahh How did I not think of that?! ”

Lin Yu said with a smile: "Master Niu was imprisoned by my drawings, so he didn't think of this matter. If you make shoes, Master Niu will definitely think about the problem of comfort, and I don't need to remind you. ”

"Where, I didn't expect it, I didn't expect it, you don't have to coax me, girl." Master Niu said embarrassedly, but he realized his mistake very well.

"So, we can make the upper part of the belt wider, or even let's make it into a tube, and then stuff it into cotton, and then flatten it and walk a few more lines, so that it will be comfortable and acquainted again. In the lower part, we can use a thinner belt, which is also sewn in two layers, but there is no need to stuff cotton, as long as we walk a few more lines to ensure that it is strong. Furthermore, our backpack is used to hold things, let's take books as an example, it will be very heavy if you load too much, so the bag must be acquainted. We can't use ordinary needles and threads, but threads like the soles of shoes. To tell the truth, our backpack is not for the rich to be carried by the lord and wife, but by ordinary people, so we don't pursue good looks, but it must be strong. Good quality and practicality, so that everyone will accept it, and we can open up this market. ”

"Wonderful! Wonderful! Yang Yi said, "After all, rich people are a minority, and rich people don't need their own backpacks." Therefore, the main consumer group of our bag is ordinary people! (To be continued.) )
