Why can't we catch fish and spend money?

We often fish, and sometimes the problem is that others catch fish again and again, but they just don't fish, or they catch fish again and again and others just don't fish. So do you really know why? It may have been mentioned briefly in the article before (not specifically, simply described), so we are in the same water area, most people catch fish, but they or a few people can't catch fish. What is the reason?

Bait: there are both similarities and differences in bait, which should be analyzed from the nature and smell of bait.

Fishing tackle: mainly depends on the hook and the drop to see if the hook sinks into the water.

Fishing method: if it is bottom fishing, change to hanging fishing, if it is hanging fishing, change to bottom fishing.

Fishing point: If the terrain is different, find a fish nest or fishway.

Distance: shallow water becomes deep water or deep water becomes shallow water, which is influenced by many reasons.

Some fishermen just didn't find it at all. You asked him, and he said about 2 meters or 3 meters. How to fish without finding out? Finding the bottom is actually very important, or you don't know if you are looking for the right bottom, or you don't know how many fish to catch and how to catch it. You must first find out what species are in the water, the size of the fish, the depth of the water and what the target fish you are going to catch. Then determine the fishing tackle bait step by step. According to the size of the target fish, determine the fishing group (main line, secondary line, hook, buoy, lead pendant) and so on.
