What allusion does Fan Dan's family portrait come from?

This is the first sign of Yan Fang, the Giant Bull, which is called the Forward Sign. If it's not my daughter's signature, I won't get the signature of two thousand gold. The eighteenth sign, the face of the sign is: if the market is crowded, why worry, take advantage of it from now on and don't have to follow. Jieyue: The security door is blessed, carefree, happy and safe. The one who signed and canceled the signing said that your signing could be counted as four, although I didn't know which signing was four. It means there are auspicious clouds at home, so don't worry about anything. From now on, you can change from less to more, and you don't need to tell your fortune or anything. It means that the whole family is fine. This allusion is a family portrait of Fan Dan. I know this story. Fan Dan is Shi Chong's son-in-law. She has a good personality. She used to be poor, but later she became rich. How exactly? I don't know So I went to Baidu, and Du Niang was really omnipotent ... It turned out that Fan Dan went up the mountain to chop wood for rice every day. One day, when he saw fish in the river, he went to catch fish and wanted to cook it for his mother. As Shi Chong's daughter was driven out of the house by Shi Chong, Shi Chong fell in love with Shi Chong at first sight and followed her to her home, hoping to tie the knot. Seeing that Fan Dan's family was poor, the barren woman took out money to let him buy rice and food. When Fan Dan saw it, it turned out that it was gold and silver, so he could change things. Before, he only cut wood and cooked, but he didn't know that every day when he went up the mountain, his left foot stepped on gold, his right foot stepped on silver, and the mountains were full of gold and silver. So I moved back and suddenly became a rich man, equivalent to hundreds of billions of RMB. Later, the house was built, and the carpenter made the door, but the carpenter refused. He said that only Master Lu Ban can install this door in your house. You will go to the river at a certain time in a certain month, and a door will float, just like it, which was made by my grandmaster. Just come back and install it. So that day, the couple went to the river and saw the door. When they came back, their home suddenly became more magnificent. Birds came to Korea, and Shi Chong came to see them, feeling ashamed. There is a saying: Shi Chong is the richest man in the world, not as good as Fan Dan.
