Fishing, hooks and lines. Excuse me, what fishing line is this? This is the first time to use this foam float.

Just insert the floating ball into the black floating ball seat (the long black beans on both sides are called space beans, which are used by the card owner to sit on the floating ball. The distance between the two space beans, whether up or down, should be controlled within a few millimeters and cannot be separated too much). The iron under the lead pendant is called the eight-character ring, which, like the number 8, can be rotated to prevent the sub-wires from being twisted together. It's called a release ring. It's very elastic, like a rubber band. Its main purpose is to prevent the fish from breaking the line tied to the hook after catching a big fish. Hooks don't slide back and forth like that. Two hooks should be tied to the release ring and kept up and down. The distance between the two hooks is about one to two centimeters.
