1. The untwisted sub-line is connected to the figure-eight ring: Step 1: First, adjust the distance between the two hooks, then fold the sub-line in half and pass through the figure-eight ring. The sub-wire pas through that figure-8 ring is wound on the sub-wire which doe not pass through the figure-8 ring and passes through the re. Pass the double hook through the sub-wire folding ring, and gently pull the double hook to fix the sub-wire on the splayed ring.
2. Knot the sub-wire to connect the eight-character ring: Step 1: The knot sub-wire can directly pass through the eight-character ring without adjusting the double hook distance. Step 2: Wrap the sub-wire passing through the figure-eight ring around the non-penetrating sub-wire for 2-3 turns and then pass through the ring. Step 3: Fix the sub-line passing through the circle, gently pull one end of the double hook, and slowly tighten the sub-line.
The secondary line is a section of fishing line (sometimes called hand line group) connecting the main line and the hook in fishing tackle, also called foot line, brain line or mouth line.
The number of sub-lines used is usually less than that of the main line (that is, the Taoist system), which is generally 0.4-0.8 times that of the main line. The purpose of using the auxiliary line is to ensure the unnecessary tension and tension of the main line when hanging the bottom or catching big fish (for example, the main line 1.0, the auxiliary line can be 0.6 or less, and the fishing group will break the auxiliary line because of excessive tension to protect the main line and its accessories). The quality requirements of the branch line and the main line are different: the branch line is required to be more resistant to curling, softer, less entangled and easier to enter.
