How to control the hook distance of the minor line?

Tie the hooks at both ends of the sub-wire first, and don't hang them in the hanging box (knotting will hurt the wire and reduce the strength of the sub-wire). Then, tie the auxiliary line to the eight-character ring of the fishing point, and the hook distance between the two hooks shall be based on the length of the two hooks or three hooks. I can't describe the way to tie the eight-character ring. You can read more posts, there are many.
