How to adjust the drift for fishing in flowing water

Two tuning methods, one is half-water with bait drifting, let's say with bait tuning five eyes, fishing six eyes, against the current to the top of the fishing point, the hook bait in place will be moved with the running water, move a distance after the rod for bait to re-fight; the second method is to fish the runaway lead, add weight to the lead, so that the lead drop to the bottom, open the lead on the space bean, fishing six or seven eyes, because there is a fixed lead drop, the hook bait can be fixed, into the water with the running water after the line is flushed to the floating lead, the floating will slowly disappear into the water. After entering the water, with the running water, with the lead to the float of the fishing line, the float will slowly into the water, and so the float is not in the water, the rod gently lifted to the float out of the water, and then put down, repeat this action three or four times after lifting the rod to replace the bait to play again.
