I use Fengxian Xiao's fishing line for recreational fishing, but it is not suitable for black pit or competitive fishing. I've used both Mo and Zhen, and I've never measured whether the fishing line is on or not. The main line (1.5-5.0) is hard and not flexible enough, and the secondary line (0.6-3.0) is easy to curl and deform. Personally speaking, leisure fishing is very good, because it doesn't change lines often and the price is cheap.

The above pictures are screenshots of some purchases, and these lines have been used for leisure fishing.

Personally, I prefer Chinese and western fishing lines and Ximandou Black Pit Line. In addition, Chinese and western shadow silkworms are also more suitable for leisure fishing, and they are not suitable for catching fish in black pits.

Personally, I prefer the Black Pit Line between China and the West and the Black Pit Carp that I recently enjoyed a lot.

It's expensive, but you don't need to change the secondary line often. You'll be glad to get one in the dark pit.
