If you see this kind of insect under the stone, don't let go of it. It's commonly known as the urine-stopping dragon. It's now expensive.

When I was growing up in the countryside, there were no toys at home at that time, only a black-and-white TV set. When there was no TV set on Tuesday afternoon, our friends would run out to play, go to the mountains and go to the river. To find something strange, that's the fun we had when we were kids. Today, I would like to introduce to you a kind of bug that grows under the stone in the river. It is the climbing sand bug. When we went to play in the river when we were young, we were always most afraid of this kind of bug.

The sand crawler looks very ugly, and it is very similar to the centipede. It has many legs and antennae, which makes people feel as if it is poisonous. When we were young, as long as we opened the stones in the river, we could always see a lot of sand reptiles. At that time, we hated this kind of bug most. We just caught some fish and shrimp in the river and brought them back. In fact, this sand-climbing worm is of great nutritional value. It is said by the old man that this sand-climbing worm has a good effect on bed-wetting. Both children and the elderly can eat it. And this sand crawler also has a nickname, called "diaper dragon", which means it can intercept the worms that pee. If the worms don't sound good, they use dragons instead.

Now people's diet is more and more diverse, a lot of things are willing to try, especially in the southern part of our country, there are a lot of dark cuisine, of which sand crawler is one. Now the sand crawler has gone to people's dining table, and it has also become a favorite food not only in China, but also in Japan. The Japanese call it "Sun Taro worm", which is a blindly nourishing medicine. The nutritional value of sand reptiles is very rich, with a strong effect of nourishing yin and nourishing yang, so both men and women, sand reptiles are nourishing. And the latest research shows that sand crawlers contain a variety of nutrients, after people eat, it is also very good for health. So now sand worms are becoming more and more popular.

In the past, there were a lot of sand worms, but people at that time were afraid to eat them. Now people's diet has changed and they began to eat sand worms, but they found that there were fewer and fewer sand worms. Now catching a sand crawler in the river is as difficult as winning the lottery, and the price of this kind of thing with high nutritional value and scarcity has been raised many times. And now the artificial breeding cost of sand reptiles is high, so the price is very expensive, usually can be sold for 200 yuan per jin, if a single sale, the price is about 10 yuan, it can be said that the price is not cheap. If you see it under a stone, don't miss it.
