How long is the traditional fishing rod wind line?

The length of the main line is generally the same as that of the fishing rod, and the length of the secondary line is generally between 20-30 cm. Therefore, the total length of fishing line is less than the length of fishing rod plus 30 cm. The fishing line is too long, which is not conducive to the accuracy of throwing fishing rods. If it is short, it will affect the distance of the fishing point. Fishing is generally bottom fishing, and the setting of floating position depends on the depth of fishing point. A line group can only have one float (vertical float). If a seven-star float is used, 5-7 floats are a group.
