How about a single line and a double hook?

I get it. What you're talking about is actually a way to tie a string of hooks. It's just a hook. I can't take pictures. I can't say clearly. I might as well search for a way to tie a string of hooks. Just string a hook. Narrowing the distance between two hooks is what you said. There's another way. Here, we call it up and down hook as follows. Then make a hook with the remaining thread. The distance between the two hooks is 5-8 cm. Lead wire is wound between two hooks to make a Zhui Er. There is no difference between the main line and the brain line. After the hook descends, the lower hook sinks to the bottom. The hook is about 3 cm from the bottom. The status is vertical hook. Hook tip up. The lower hook can be hung with bait or empty hook.
