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

Little Fatty's grandma, seeing this, frowned and muttered, "You child, why did you secretly put this thing in your schoolbag? You're not allowed to play with it in class!"

Little Fatty quickly explained, "Grandma, I'm not playing with it. I'm going to trade it with Sister Ya for some grass-woven insects. I promise I won't play with them in class! Look at them, everyone else is trading them. If everyone in our class has one and I don't, how embarrassing will it be for your grandson?"

Grandma Xiaopang, half-believing, peered behind the worktable and said, "Oh, you're changing to this? It's an old craft; not many people know how to weave these days. Okay, you can change it."

The chubby boy grinned.

Grandma Xiaopang didn't rush back to her seat. She stood to the side with her hands behind her back, watching the commotion. Seeing that everyone else was exchanging their Xinhua dictionaries, teaching pinyin and character recognition, reciting poems, and reciting multiplication tables, she reached out and rubbed her eldest grandson's short buzz cut.

The prickly texture felt like kneading a kiwi.

"Look at you! You never listen in class and never do your homework properly. Other people earn things through knowledge, but all you can do is offer toys. And you might not even be able to get anything. Now you understand what the point of knowledge is, right?"

The chubby boy looked dejected and replied with a wry smile, "Okay, Grandma."

He turned and handed the blue box to Ya Ya: "Ya Ya, take a look at this, can I trade it with you?"

Ya Ya tilted her head and examined the square box in Xiao Pang's hand. The lid was transparent, and she could see some colorful cylinders inside, which looked a bit like chalk. They were quite pretty.

"Little Fatty, what's this? Is it a pencil case? I have one! Brother Zhao gave me a whole set, it has erasers and pencils, and I have lots of chalk too."

"It's not a pencil case, it's not a pen." Little Fatty was startled. Luckily, what he had brought wasn't stationery but a toy, otherwise he might have had to exchange it for something else. He quickly opened the box and pulled out a pale yellow cylindrical object, placing it in his palm.

"This is called super light clay. It's similar to Play-Doh, but much lighter and not sticky. You can mold it into whatever you want, and you can even combine multiple colors. After you've finished molding it, leave it in a clean place to dry for two days, and it will harden and won't deform. It will become like the decorative piece that Xie Yuan brought over yesterday."

As he spoke, he demonstrated, rolling the clay into long strips and small balls with his hands. Finally, he stretched the clay block into a very long length, just like the ramen makers on TV: "Look, it can be stretched this long even without sticking to your hands."

Ya Ya's eyes lit up. This was just a clean, colored lump of mud!

Before Uncle Zhao laid the rammed earth in the front yard, little Shuanzi would always squat in the corner, digging at the mud and making little stoves, little mounds, and little houses. Because they were so small and the same color as the ground, his grandparents, whose eyesight wasn't good, would often stomp them flat and he would have to make them all over again.

With this little shovel, I don't have to play in the mud every day, and I don't have to worry about my grandparents not watching me. The mud here is such a bright and vibrant color!

And once dried, they can be used as beautiful decorative items—beautiful items you made yourself. They'll definitely look good placed in the yard or inside the house.

Those few red lumps, the light red ones can be used to sculpt a Peppa Pig, and the darker ones can be used to sculpt the pig mount of Taiyi Zhenren.

This box is so big, I can make so many!

Ya Ya was delighted, her eyes fixed on the blue box in Little Fatty's hand, but she also felt a little guilty: "Little Fatty, you're trading such a big box with me, aren't you going to lose out? How about I trade you two, the big ones?"

Little Fatty waved his hand, "It's okay, it's okay, this box only costs a few dozen yuan." As soon as he finished speaking, he fidgeted and poked his finger, "Sister Ya, if you really want to give me more, I... I can do it too. I'll take a smaller one, and then I can teach you a little bit of the multiplication tables."

As he spoke, the chubby boy racked his brains for the few multiplication rules he had learned: "One times one equals one, one times two equals two, one times three equals three. That's all I know."

Ya Ya looked blankly at him: "Little Fatty, what are you talking about? A punishment incantation? Do you recite this before punishing someone here?"

Xie Yuan chuckled: "It's not a punishment, it's multiplication, it's used for arithmetic."

"How do you use this multiplication table to do math? One times one equals one, one plus one equals one, one plus two equals two, one plus two equals three, right?"

The chubby boy opened his mouth, but then got stuck.

He could only recite two simple rhymes without being able to explain the underlying principles.

Zhou Zihan, standing at the back, raised her hand: "I'll do it, I know! Sister Ya, I'll teach you!"

Little Fatty voluntarily gave his seat to Zhou Zihan.

"Multiplication is a kind of arithmetic method similar to addition and subtraction. Once you learn it, it saves a lot of trouble and makes calculations super fast. It's like..." Zhou Zihan looked down and took out three packaged clays from the chubby little guy's super light clay box.

"Let's say a piece of clay costs eight yuan. The price of three pieces can be calculated using the multiplication table: three times eight equals twenty-four, which is twenty-four yuan. If you don't know multiplication, you have to add them one by one and count them over and over again."

Ya Ya's eyes lit up instantly: "There are such useful arithmetic methods! Can someone teach me? I want to learn this."

Xie Yuan immediately raised her hand high: "Me! I've memorized the entire multiplication table!"

After saying that, she felt a little guilty. If she took on all of these, the other students wouldn't get many to exchange, and she already had three...

Seeing this, Zhou Zihan hesitated for a moment, then raised her hand as well: "I know quite a lot too. Can I teach you as I learn? I'll take two!"

"Okay, so what should I call you?" Ya Ya nodded and generously opened her backpack to let the little boy with neatly arranged hair on his head, which looked like a small black bowl, pick it up.

"My name is Zhou Zihan."

"Okay, Brother Zihan."

Not far away, Zhao Haohao, busy wielding a ladle, perked up his ears. In just a short while, Sister Ya had gained two more older brothers. But thankfully, neither sounded as prestigious as Brother Zhao; he was still the eldest brother.

The remaining group of children also came up one by one to exchange items. Some took out small toys, cartoon keychains, and blind boxes, while others took out their pocket money. One of them even recited a poem on a quiet night and exchanged it for a small insect he liked.

Parents watched their children frantically searching their minds for the knowledge they had learned, nodding approvingly with satisfaction in their eyes. This exchange was wonderful; they would definitely come to this store every day from now on.

Kids love being little teachers, and this place not only lets your child experience the thrill of teaching others, but also helps them reinforce and review what they've already learned. Plus, there's delicious, nutritious soup noodles—it's a complete spiritual and material enrichment.

What a treasure shop with excellent feng shui!
