Zi is a pictophonetic character, and the upper part of Zi is a net. The mover is to tie four poles into a cross, hang them on a main pole, hang the fishing net on the top of the four poles, adjust the angle and direction from time to time, sink into the water, and pull them up with ropes every minute or two, and the fish just swims over the net and is caught.
Mobile fishing is the action of constantly moving this special fishing net. In fact, moving fish is a form of labor that moves this ancient fishing tool.
Fishing with nets is usually carried out in small rivers, even in large rivers, on the banks of rivers, and rarely in the middle of rivers.
What kind of river reach or river bank can raise fish, and you can't touch it. You must make an observation in advance, make a certain judgment based on experience, identify where there may be fish, and then get off the net, so that you have more chances of winning.
The best time to transport fish is when it has just rained heavily and the river is turbid. At this time, the fish are more concentrated than usual, or at the intersection of hot and cold water above the weir head and at the entrance of the branch canal, often every net is empty.
