How to adjust the drift of black pit

First, after the nest is painted, the bait has been fishing and floating. I don't know if it's the bait or the adjustment of fishing method, or if the bait falls into the mud bottom of the sauce layer, the patient will continue to stick to it, impatiently fine-tune his mouth, and even need to re-open the bait to find the taste.

Second, not long after nesting, it kept drifting, but I couldn't grasp the truth. If I lift five poles, maybe four poles are empty, and the other pole often runs away from the fish. According to the basic judgment, either the bait tastes wrong, the fish are extremely wary of the bait, or the drift is too smart and there are too many false signals.

Third, fishing is correct and the connecting rod is straight. This is the ideal state, the probability is small, but it is also very common.
