In the fishing villages in the Jiangnan water town, the life of living on the water should be rough but stable, but someone wants to stir up a ridiculous situation in the choking smell of fish. She was guarding a dilapidated fishing boat, just to cast a net to catch fish for food and clothing, but unexpectedly she picked up a poor young man who fell into the water, and discovered the government's hidden secrets of smuggling fish. Even when she was on the sea, she could get involved in the secret calculations between her neighbors. Every trip to sea is a gamble. If you win, you will have a cabin full of fish and shrimps. If you lose, you will be in trouble. But she relied on her unfailing energy to make life in embarrassment a joy in the ebb and flow of the tide. In the water town where fish and dragons mingled, she used the most down-to-earth method to shake off the dirty, absurd and ridiculous things under the water's surface with a net of fish and shrimps. The days are wrapped in the smell of fish that cannot be washed away, but in the midst of laughter and curses, I live a unique life.
