When I was a child, I often saw this "drift" master in the countryside, but I didn't expect it to be a blindly traditional Chinese medicine.

When I was a child, there were not many places to play in summer in the countryside. When the weather was too hot, I liked to find a place with water to play. I often saw a kind of bug floating on the water, but it was very difficult to catch. It was no exaggeration to say that it was a master of "drift".

In my hometown, this kind of bug is called "Yan Ye". Compared with other bugs, this one is not disgusting, but rather popular. When I was a child, I especially wanted to catch one with my own hands, but it was so fast that it was really difficult to catch.

According to the old man, this kind of insect is still beneficial and can eat the eggs of other pests in the water. For example, mosquitoes like to lay their eggs in the water, and Yan Ying can eat part of them. In addition, Yan Nian also likes to eat some plankton on the surface of the water, which can purify the water quality.

"Yan Yue" is not only a beneficial worm, but also can be used as a traditional Chinese medicine to treat all hemorrhoids.

Have you ever seen this kind of bug? What do you call it in your hometown?
