There is a folk trick for catching eels, which only requires a cage made of bamboo. The strange thing is that the cage has a big hole, and the eels can't get out after they get in. Why is this?

You must have never seen how to catch eels with this Louzi. I will tell you the steps and principles:

1. First of all, eels have slippery bodies and like to drill.

2. Taking advantage of this feature, fishermen made the Louzi you see. The large opening below is not the entrance to lure eels in, but the opening where bait is put in and the eels are taken out after catching them. The entrance of the cave The size is generally enough to fit into an adult's hand.

3. At the top of the loaf (sometimes on the side), there is a small funnel-shaped opening made of bamboo pieces. The bamboo sheets are bent and closed inside the loaf, and are braided in a way that they gradually become smaller from the top, so that , eels can drill into the roof through the small opening at the top.

4. After the bait is put in, the large mouth at the bottom will be covered with a lid made of wood or bamboo, and placed in the place where eels hang out. The eels will be attracted by the bait and drill in through the small mouth at the top. Because their bodies are very small, It is slippery and it is easy to enter the Louzi. After eating the bait, you can't find the exit if you want to get out. Due to the elasticity of bamboo, the closing area is easy to enter and difficult to exit, so it becomes a turtle in the urn. After the fishermen collect the eggs, they open the bottom cover and the eels are declared as trophies.
