May I ask: how to connect the rod tip to the main line?

I've used this method when I was fishing traditionally, and I feel that there are a lot of problems with it: it is easy to tangle the line; the rod tip rattles too much; the link ring is too small; it is easy to break after using it for a long time, etc. I don't recommend this method. Personally, I don't recommend this method. The pig's feet buckle is easy to entangle the line note if the buckle is too long to help buckle control in 4-5 centimeters is most appropriate, the fishing line knot do not pull too tight so that when you use it will not be easy to break from the knot ......
