When fishing, do you mean hook bottom or lead?

This situation is more complicated. According to your fishing method, environment and choice of target fish, traditional fishing method leads to the finish line and Taiwan Province fishing method leads to the finish line. If you catch semi-aquatic fish such as bighead carp and grass carp, you can adjust the hook to about 1 m underwater. If you fish in running water or drifting, you don't have to fall. The bottom of the fishing must fall to the bottom with lead, otherwise it will be washed away by the water.
