I like to invent fishing hooks on TV. What is it like?

I don't remember if this is it. This kind of hook is not the first. There is another kind of hook that Europeans use to fish. This kind of hook is similar. It is a kind of fish, which is widely used, but there are few fishing spots in pure wild environment in China, which is not suitable for many fishermen. Figure 2. Big fish will eat this kind of hook. The area where small medicine and commercial bait are widely used is unique, but the effect is not high. Have you practiced?
