The fisherman stood up and wiped the bamboo pole beside the boat. All the cormorants flapped their wings and went into the water. The lake immediately lost its calm and rippled in circles, and countless waves jumped in the soft light of the sunset. Before long, the cormorant surfaced, flapping its wings and jumping on the fishing boat, with a bulging throat. The fisherman grabbed it by the neck, squeezed out the fish swallowed into the throat bag and threw it into the water. Cormorants keep jumping on fishing boats, and fishermen are as busy as a bee. When smoke came from the kitchen on the shore, the fisherman stopped driving the cormorants into the water and stopped them by the boat. He picked out some small fish from the cabin and threw them to the cormorants one by one. The cormorant opens its long mouth, grabs the thrown fish and swallows it in one gulp. Cormorants are full and stand neatly beside the boat like soldiers. The fisherman paddled back to his boat. The following is a series of dynamic descriptions of fishermen and cormorants.
