A Grave Sin

In the final years of the Qing dynasty, the people of Guanzhong lived in abject poverty under the incompetent rule of the Qing government. While fleeing famine, Xizi's father was killed by bandits. After the landlord couple, Liu Maocai and his wife, rescued him, he stayed on as their hired hand.
