His name is Yang Boyong. He is young, diligent and kind-hearted. Seeing that the passing passengers trudged through this place and lacked a place to rest and drink water, he set up a thatched pavilion for the passing passengers to drink water and drink tea. He has been single for three years. One day, an old man with a stone on his back fell down in front of the pavilion because of overwork. Yang Boyong quickly lifted the old man up, fed him water and saved him. Yang Boyong asked about the cold and warmth, and wanted the old man to stay for an extra hour. The old man said, "I have something to do. I can't stay long." Then he put a bucket of stones on his back and said, "Don't look at these stone heads. If you plant them in the ground, you will produce jade and marry a good wife. " Before Yang Boyong thanked him, the old man disappeared.
Yang Boyong did as the old man asked, and sure enough, a bucket of jade was born in the field. Later, he made five pairs of white jade as a dowry and married a kind and clever girl, Xu. However, there are few mountains in this place. In the face of drought, grain production is reduced, and farmers are starving and miserable. After consulting with his wife, Yang Boyong gave his jade to the people who went down the mountain in exchange for food in the disaster year. The news that the poor villa produces jade spread like wildfire. For a time, officials and bandits colluded and robbed the jade in the field, and the life of the Yang Boyong family and the villagers became a problem. It turned out that the old man saved by Yang Boyong was not a mortal, but a Venus in white. When he learned that the jade in the field had been looted by officials and bandits, he told Yang Boyong in his dream: "In and out of Nanshan on a sunny day, the jade is hidden in the light smoke." Since then, only insiders have found gems in the mountains. Officials and bandits can only pick blue stones that don't grow into jade, which is a kind of inferior jade.
