The little one's purse connects the two worlds, turning a desolate village into a paradise.

These little black shoes may be a bit ugly, but they are sturdy, durable, and made with high-quality materials.

The little guy is quite good at managing his finances.

"Buying these for your grandparents?"

"Mmm," Ya Ya responded softly.

"You have to buy shoes according to the size, otherwise they'll be uncomfortable. If they're too big, they won't fit properly, and if they're too small, they'll hurt your toes. Do you remember the shoe sizes of the grandpas and grandmas in your village?"

Upon hearing this, Ya Ya's eyes crinkled into a smile. She took out a bundle of straw rope from her small satchel, shook it proudly, and said, "Auntie, look! This is Uncle Zhao's idea. He had everyone use the straw rope to measure the length of the rope against their feet, so I could buy this!"

Cao Xiulian's eyes lit up, and she nodded repeatedly, "This is good, this is good! Your Uncle Zhao is really clever; this is even more accurate than giving measurements!"

Hearing Cao Xiulian praise Uncle Zhao, Ya Ya was even happier than if she had heard herself being praised, her face beaming with pride.

"Since you have something to buy, go ahead. I won't keep you any longer. Drive slowly and watch out for cars."

"Mmm!" Ya Ya nodded vigorously, put the straw rope into her bag, grabbed the handle of the cart, and walked briskly toward the stall selling cotton shoes.

Passing by the meat stall, seeing the special offer sign still hanging, Ya Ya bought two more pounds of pork ribs. The soup made from the pork ribs was so delicious, she'd buy some more to put in the cellar.

After buying the cotton shoes, we'll go to the grain store and buy a bag of rice. We've finished the fruit from last time; we each only had one to taste it, so we can buy some more this time...

As Ya Ya looked around, she carefully planned her shopping for the day. When she got to the grocery section, she found that the turkey stall from yesterday was gone.

She was a little disappointed; she should have bought more.

Pushing the cart forward, Ya Ya noticed a particularly small new stall next to her. The stall owner was a young lady wearing a strange long-tongued hat.

On the stall were two carts that looked similar to the one she was pushing, with two cardboard boxes on them. One of the boxes had a sign that read: "Reading glasses, 20 yuan a pair".

Another cardboard box had "Buy one get one free" written on it.

The box was full of packaged glasses, and a few pairs were even unpacked and used as samples.

Ya Ya stopped the toy car and stared curiously at the strange object. It was a black frame with two circles inside and two round, transparent pieces, with two thin sticks trailing behind it. What was this?

The young woman noticed the child pushing the stroller but didn't greet him. Such a small child clearly couldn't have presbyopia and wasn't her target customer.

He just kept eating the meat bun in his hand.

A short while later, an elderly man strolled over slowly with his hands behind his back. The young woman's eyes lit up, and she quickly stuffed the bun into her mouth, immediately greeting him warmly.

"Grandpa, grandpa, come take a look! We just got some new reading glasses, only 20 yuan a pair, buy one get one free today, what a great deal!"

The old man's eyes lit up immediately when he heard "buy one get one free," and he leaned forward to examine them: "These glasses look pretty high-end in packaging."

"That's right!" the young woman said with a smile. "These are resin lenses, very light, and they also block blue light and radiation, so they won't hurt your eyes. Most importantly, when you wear them, you can see small print and your phone clearly. For older people with poor eyesight, they'll help immediately!"

As soon as these words were spoken, Ya Ya, who had been silently watching the spectacle, also lit up and pushed her little cart over.

It makes reading small print clear, and it's especially helpful for older people with poor eyesight...

When Grandpa Fang was looking at those small prints, his eyes were practically glued to the paper. Should we use this too?

She tilted her little face up and asked softly, "Sister, my grandpa has to get really, really close to the words to read, and he keeps rubbing his eyes after a while. Could you use these glasses to help?"

Before the young woman could reply, the old man picked up a pair of reading glasses, hung them over his ears, and perched them on the bridge of his nose. He then took out his phone and opened a novel app. "Wow, these are so clear! They're much better than my old, scratched ones."

"Give me two sets."

The young woman smiled and packed two pairs of reading glasses for the old man, watching him leave before turning to Ya Ya and asking with a smile, "Little one, are you buying these for your grandpa?"

"Yes, sister."

"Most older people have presbyopia. This isn't expensive, and it's buy one get one free. Why don't you buy it and let your grandpa try it on? From what you've said, he probably has presbyopia."

Ya Ya tiptoed and looked at the glasses in the box: "What is presbyopia?"

The young woman was momentarily speechless, but after thinking for a moment, she explained, "It's just that I'm getting old, and my eyesight isn't good enough to see small print up close, but I can see things from a distance. These glasses can help."

Ya Ya said "Oh". Grandpa Fang usually doesn't seem to have trouble seeing, but his eyes get blurry when he looks at words. It must be the presbyopia that this young lady was talking about.

This place is great! There are flashlights that can light up, turkeys that can shoot fire, and now there are even reading glasses that can help people see clearly!

She thought of Grandpa Wang from the village and asked earnestly, "Sister, do you have any glasses here that can help people who are completely blind to see again?"

The young woman chuckled, "No, if you can't see at all, you'll have to go to the hospital. Reading glasses won't solve it."

Ya Ya nodded as if she understood, "Then let's buy reading glasses first."

After putting two pairs of reading glasses into the cart, Ya Ya pushed the cart further in and soon saw the lady selling cotton shoes at the usual spot.

"Little one, you're here?" The woman selling cotton shoes waved enthusiastically to Ya Ya.

"Auntie!" Ya Ya responded obediently, her little face beaming with a sweet smile. "Your cotton shoes are so comfortable, warm and sturdy, and your socks are so soft and cozy!"

The older woman chuckled upon hearing this, "You're so sweet! Did you measure your size? Auntie will bring you a few more pairs of socks later!"

"I've already measured them out. I don't need the socks anymore. Auntie, you work so hard to earn money. You should keep the socks to sell. I've already given Ya Ya a lot!" Ya Ya said, pulling out a straw rope.

"Hey, it's not like it's free. You bought so much from me, what's wrong with giving me a couple of pairs of socks? Do you remember the size? Tell me, and I'll pick some out for you." The older sister grabbed a handful of socks and put them directly into the bag.

"The grandpas and grandmas in the village don't know the sizes, but Uncle Zhao came up with a way. He used straw rope to measure the length of each person's foot. Could you please help me get the shoes according to the length? Thank you!" Ya Ya held up a bundle of straw rope and handed it to the woman selling cotton shoes.

The shoe seller took the bundle of straw ropes of varying thicknesses and lengths; they were all freshly hand-twisted straw ropes.

Twenty in total.

This method is interesting; she's never seen anyone buy things this way before.

She thought that at most, the villagers would write the measurements on a piece of paper and have the little girl bring it over.

"Okay, Auntie will pick them out for you based on this." The eldest sister took the rope without minding the trouble, squatted down and quickly picked out and compared pairs of shoes. In no time, she had filled the box in Ya Ya's little cart with pairs of thick black cotton shoes.

It was packed full and still had some sticking out.

The lid of the box can't be closed anymore.

She pressed it down and stuffed the small bag of socks inside.

"Alright, that's twenty pairs in total, three hundred."
