What do the main line and the auxiliary line of the fishing rod refer to respectively?

The main line is used for stress and assembly.

Connect the sub-wires through the splay ring or quick connector.

The main line is generally as long as the fishing rod.

Sublines are generally 20~40CM long.

Hook the auxiliary line

The secondary line is generally thinner than the main line, such as 0.4~0.6 secondary line +0 of the main line 65438.

The auxiliary line can protect the main line from damage when it breaks, runs away from fish or hangs on the bottom of the water.

The thinner and softer the subline, the easier it is for fish to take the bait, and the more obvious the entrance signal is.
