Net fishing is the earliest method used for collaborative fishing, operated by two bamboo rafts or sampans at the time. When fishing net is threw from the boat, those on the shore will try to pull the net up not by hands but by the force generated through the rope tied on waist and backward body movement. Every one that joins the fishing, regardless of ages and genders, is able to take one share of the catch, so "net fishing" is also nicknamed "bonus sharing of rope." There is also a saying: "Every one has a share in net fishing, and the pregnant one takes double."
