What is the story of warm fish lying on ice in The Analects of Confucius?

Sleeping on ice is a carp, which comes from the twenty-four histories. Legend has it that Wang Xiang lost his father's love when his mother died young and his stepmother Zhu spoke ill of him many times in front of his father. My stepmother is ill and wants to eat carp. It's freezing, the river is frozen, and it's impossible to fish. Wang Xiang let bygones be bygones, so he made a plan to unbutton his clothes and lie on the ice. Suddenly, the ice melted by itself and two carp jumped out. After eating, the stepmother really recovered. People say that Xiaogan Heaven and Earth will be blessed by God.
