How many meters to buy a hand pole is good, usually river fishing. How many meters do you use?

Hand lever 16m. Anyway, it's a long pole in Shanghai. If the short-term feeling is too long, you can put away the later sections. If it is long, it will be too tired to throw it away. If you want to feel that the river is too big and the fishing rod is too long to fall off, I suggest you buy a 4.5m rock rod directly. Throwing it is definitely not more tiring than a 7-meter fishing rod.
