Traditional fish rubber band bin method

It is often used on long poles over10m, and the length of rubber band is generally1.5-2m, which is fixed on the pole tip, and then the line is tied on the rubber band. The rubber band is hollow and I bought it in a fishing gear shop. Long poles generally use short lines (about 3 meters) instead of rubber bands. When you meet a big guy, it's easy to tangent or tug-of-war to run for fish! Adding a rubber band can play a buffering role. In southern Jiangsu, fishing is basically done with long pole grass, and it is difficult for fish under 20 kg to run!
