After that, Chu Jiaqiang caught two more fish and "visited" the litter of fishing cats. Those little fishing cats always wanted to come over to play with Chu Jiaqiang, but the big fishing cats yelled back every time, and all the disobedient ones were taught a lesson.

In the afternoon, Chu Jiaqiang saw several children walking by the door carrying a big bamboo pole. The bamboo pole was probably nearly twenty meters long, and I don't know what the hell these kids were up to.

Now that it's all on holiday, these little guys know all day long, digging birds and fishing, anyway, the little creatures in the village have been killed. There are also many people who follow those tourists to run around, take people to play, and make some big money to spend, in fact, it is more than ten or twenty yuan, but for them, it is really a lot of money.

"What are you doing here?" Chu Jiaqiang asked, he found that there were still some tourists following, and he knew that these guys were ready to trick or treat again.

"Let's go pick oak nuts and make some spinning tops to play with." A child replied. Then he asked, "Uncle Qiang, are you coming?" ”

"Oaks? What oak fruit? Can you make a spinning top? The third Zhou Furong asked.

Chu Jiaqiang pointed to a big tree in the distance: "No! It is the oak tree, which is also called an oak tree by outsiders, and their fruit looks like a spinning top, with a big thumb, and you can make a spinning top to play with by wearing a bamboo stick. ”

It is a tall tree, which is very spectacular from a distance, and it is one of the few century-old trees in Chujiazhai. When you get down there, it's a bit of a cover-up.

At this time, some of the leaves of the oak tree had begun to turn brownish-red, and if you didn't look closely, you thought it was a maple tree. This is also one of the few deciduous trees in Chujiazhai, which changes greatly with the seasons, and will be like a maple tree in autumn and bare branches in winter. When he was young, Chu Jiaqiang thought it was dead.

"Oh! It turned out to be an oak tree, go, let's go and see it too. Looks like it's fun. Zhou Furong said. At first, he really thought it was a maple tree, but he was a little shocked that there was such a big maple tree.

Come under the oak tree. Everyone really felt the height of the oak tree. It should occupy an area of three or four acres, and look like forty or fifty meters high, underneath. You can't see the sun shining down at all, and it's densely packed with leaves.

"I'm afraid this bamboo pole is not tall enough!" Ye Jisheng looked at the bamboo pole and said.

"You can only knock on the bottom, and don't make up your mind on the top." Chu Jiaqiang said. He didn't bother to do it either. Just look for it on the ground around you. In the past, you could pick up a lot of them, especially in late autumn or winter, when the wind blows, and the leaves and fruits fall.

"This oak tree doesn't seem to be the same as our northern ones." Li Xiangdong said.

"Not surprisingly, there are several species of oak trees in our country alone. How many are in the world, I don't know. Chu Jiaqiang was not surprised. Except for some solitary plants, endangered plants, there are almost many other species, and there are great differences between north and south, and even the same province may also cause different plants due to terrain differences.

I saw Chu Jiaqiang looking on the ground. Many tourists also search in the carpet style. It didn't take long. Before Chu Jiaqiang could find it, someone found it first.

"Hmmm! It's kind of like a spinning top. But it's so small, it shouldn't be fun! I still found it back and fried it, and it is said that this thing can be eaten. Zhou Furong said.

His words are not groundless, acorns are indeed edible. The fruit of the oak tree, the acorn, is particularly recognizable as a nut. The fruit is protected by a cup-shaped shell. It is called a shell bucket. It is rich in starch, which can be used to make oak, alcohol, starch, rubber oil, etc. Some even use it to make feed.

Of course, these are all outside practices. The countryside knows that oak nuts can be eaten. But adults never take it back to eat, and they don't have that free time, which is very troublesome. First of all, it's not easy to knock it down, this pestle is here, everyone can see it, it's so high, it's not easy to climb. Secondly, you have to get rid of that hard shell, which takes a lot of work, and it is better to grow sweet potatoes honestly.

In addition, most people in the countryside do not know that acorns have other functions. It's the children who figure out how to play, play with the spinning top, and have fun.

When it comes to the use of oak trees, in fact, it is also a treasure all over the body, and it has a wide range of uses. Wood is a strong and corrosion-resistant timber, and bark, leaves, shells, and extracts are essential for tanning, printing and dyeing, and fishing.

A few days ago, Professor Wen and others also noticed this huge oak tree. According to him, charcoal can also be burned. The leaves of the oak tree contain water, protein, carbohydrates, fat, ash, cellulose and other components, which can be used to raise silkworms. Tannins extracted from oak bark, leaves, shells, and acorns are essential for the tanning, printing and dyeing industries, and fisheries. The cork has a thicker cortex and can be used as an industrial cork material. Oak trees can also be used to cultivate a variety of edible fungi such as fungus, shiitake mushrooms and dense ring mushrooms.

"That's not the case, there are a lot of ways to play with spinning tops! The big spinning top has its own way of playing, and the small ones have different ways to play. Chu Jiaqiang said.

Gyroscope is one of the earliest entertainment projects in China, also known as Dhara, called "Ganle" in Hokkien, and called "Bingyu" or "Playing Old Cow" in the north. To be precise, it should be a children's toy, shaped slightly like a conch, mostly made of wood, with an iron tip underneath, wound with a rope when playing, and pulling the rope vigorously to make it rotate upright. Some are made of iron sheet and rotate using the elastic force of the clockwork.

The general way to play is like that, but in some rural areas, it is like to fill the number with oak fruits. It's easier to play, easier to make, or more suitable for small children. Just stick a handle in the middle, grab the handle when you play, and then rotate the wooden handle vigorously. The strength can be big or small, unlike some regular spinning tops, a few pounds heavy, even more than ten pounds, dozens of pounds are not lacking, children really can't play without strength.

"I'll try it!" A tourist jumped to try it and took the long bamboo pole in his hands. His hand suddenly sank, and he secretly said that this kid's strength is not small! Just now, I saw that the child was knocking on a long bamboo pole flexibly.

"Get out of the way of the people in front!" The tourist suddenly shouted, and his face changed dramatically. I saw that the bamboo pole was too long and heavy on it. In addition, this tourist has no experience in catching poles, and without adequate preparation, the top will be smashed down.

The people in front of them hurriedly dodged away and joked: "Big brother, are you murdering?" ”

The tourist's face turned red: "Ahem! Careless! A momentary miss! ”

The others were sweating wildly, and Chu Jiaqiang had no choice but to tell him that when catching bamboo poles, try to catch them vertically, so that it would save a lot of effort, and the situation just now would not occur. The man tried, and sure enough, it was. The true meaning of life often comes from these details, which can only be felt by those who have experienced it firsthand.
