Do you need a bus to catch big fish without hands?

Traditional fishing method is always a line to the end, while Taiwan Province fishing method needs the connection between the secondary line and the main line.

If the main line is put down directly without the auxiliary line, the corresponding fishing rate will be lower because of the large diameter of the main line, and it is easy to break the main line after hanging the bottom. If there is a sub-line, because the sub-line is relatively thin, it can only be broken.
