Uncle Yantai is very clever. He fished through the drain, because the drain was connected to the sea, and the fish were hidden in the rocks. If the fish is hooked, there is no escape. The local people know the habits of these fish very well, so they fish in the gutter. The locals also learned to travel to Jiang Taigong, and all the fish were hooked.

Roads are built on rocks, and fish live in cracks in rocks. Tourists found uncle's strange fishing method, and the video taken by tourists to uncle, and netizens found that this fish is called black snapper. Uncle caught a lot of snakehead fish. Uncle's fishing principle is because he knows the living habits of these fish. Locals all know that this kind of fish lives in cracks in rocks. The locals also know that the road is built on a reef, so they fish in the drainage hole, knowing that there will definitely be snakehead activities here. After we learned about these situations, we realized that it was not how smart the locals were, but because they were very careful and mastered the living habits of fish, so they started fishing.

The drainage hole is connected with the sea. The uncle got so much because he fished in the drainage hole. Because these drainage holes lead to the sea, which is the only way for this kind of fish, uncle will definitely get something from fishing here. Some netizens also pointed out that if the fish is too big for uncle to catch, he can only choose to give up, because the drainage hole is small after all, so the fish caught is not big. Many people fish just for fun, not to eat fish. Some people will release the fish after they catch it because they just want to have fun.

It is said that Yantai is a city near the sea, and locals can pick up a lot of seafood even if they don't go fishing. Every time after the gale, they can catch a lot of seafood, and even fish in the drainage hole. What a wonderful thing. I hope to have a chance to take a walk in Yantai, appreciate the local customs and see my uncle fishing in the drainage hole.
