I don't think you've ever seen how to use this Lou to catch eels, I'll give you the steps and principles:

1, first of all, the eel body slippery, like to drill holes;

2, the use of this feature, the fishermen made the Lou you see, below a big mouth is not to lure eels to go in the mouth of the hole, but the mouth of the eel to put bait and catch eels to take out the mouth of the eel. The hole is usually sized to fit an adult's hand.

3. At the top of the Lou (or in some cases at the side), there is a small funnel-shaped opening made of bamboo, which is bent to close the opening inside the Lou, and the opening is gradually narrowed from the top, so that the eels can enter the Lou through the small opening at the top.

4. After the bait is put into the Lou, the big mouth at the bottom will be covered with a lid made of wood or bamboo and put into the eel-infested place. The eel will be attracted by the bait and will drill into the Lou from the small mouth at the top, and because of the slippery body, it will easily enter into the Lou, and eat the bait, and then try to come out, so it can't find the exit, and because of the elasticity of the bamboo, it is easy to enter and hard to come out of the bamboo at the closing place, and so it will be a turtle in a jar. After the fisherman collects the blunder, he opens the lid at the bottom, and the eel is declared a trophy.
