1. When adjusting the drift, no matter whether the drift tip is hollow or solid, the adjustment mark pole is fully out of water. There is no strictly set fishing eye when fishing, because the weight of a bait can pull the floating tip out of sight.

2. According to He Weilan's "residual buoyancy theory", the weight of a single bait is greater than the remaining buoyancy of the fish float. After the two baits are positioned, as long as the tip of the float is exposed to the water, you can catch as many fish as you need. Considering that the herring hook has one mesh of ups and downs, and then the drift tip rises and stagnates, and then is connected to 2 to 3 lower hooks, usually three meshes are usually caught.
