The fishing sub-line is tied as follows:

1. Tie the fishhook: Since the sub-line is connected to the fishhook, you need to first tie the fishhook to the sub-line when tying. Connected together. Since double hooks are generally used, the double hooks need to be tied to both ends of the sub-thread. By winding, wrap the sub-thread around the hook handle and wrap it 5 to 6 times more firmly.

2. Connect the figure-eight ring: The fishhook is connected below the sub-line, and the main line is connected above. It is more convenient to connect through the eight-figure ring. First tie the sub-thread to the figure-eight ring, then prepare the main thread, connect it to the figure-eight ring, and tie a knot. Finally, just cut off the excess thread produced during this process. Before use, it is best to check whether the binding is firm. After making sure it is firm, you can start fishing.
