How to adjust the traditional five-star drift?

In traditional fishing, the five-star drift (string drift) method is used:

1. Adjust the weight of lead falling in half water with the fishing group without hook, so that the floating objects are exposed to the water for 2 pieces.

2. Tie the fishing group to the single hook, hang the bait on the single hook, and let all the floats sink into the water.

3. Adjust the position of the float upward until the hook and bait touch the bottom of the water, and then you can float the fish when two pieces are exposed.

4. If the float moves but you can't catch any fish, please adjust the float upward, and the distance is the length of the secondary line (at this time, the signal of the lead falling is dead).
