The good news is that I was born into a salt merchant's family, and I will have no worries about food and clothing for the rest of my life. The water from the Yellow River comes from the sky and flies into the homes of ordinary people. It is my turn to be rich and rich. The bad news is that the mouth of the Yellow River is blocked again, and the salt fields are gone. But the good news is that my father was afraid of the refugees, so he took the initiative to open a porridge shack, and more and more people gathered. Why does my neck feel itchy? What to do? What goes north?
