The big snails in the river can be eaten

The first thing to look at when fishing in rivers is the speed of the water flow! The second is the fishing position; choose fishing waters with a water flow speed of about S\2M; fishing position selection; baits such as water plants on the backwater bends, whirlpools, reeds, cattails, under bridge piers, etc.; you can use earthworms, Grass shrimp, loach, field snail, river mussel, river crab meat, lamb liver, chicken intestines, or "pasta" (pasta is atomized, has high specific gravity requirements, and is not durable; meat bait is effective and the material is easy to fish)
