The White Dove on the Tip of the Cold Dish Poet's Knife

Li Guang, a laid-off worker, and his wife relied on a cold vegetable stall in the snack street to make a living, but their business was poor and they were in a tight situation. Li Guang bought a collection of poems that made his wife furious. Later, his son Xiaoshuai, who was mildly mentally retarded, was bullied by the "boss's son." He quarreled with his wife and started fighting, only to find out that his wife was pregnant. When he was picking up his children, he stopped a car to defend his rights but showed cowardice. He pulled out a knife and pointed it at himself. He vaguely saw pigeons taking off.
