How to adjust buoys with traditional fishing methods

What the landlord said is a bit vague ... what does it mean to use the small wire skin in the network cable as the lead holder to reduce the resistance? I don't quite understand, and whether the float is a bean float or something ... Traditionally, bean floats can also be made into pendants, but it is difficult to grasp the hook state at the bottom and distinguish the true and false signals. Float with beans or catch pendants?
