Why is Weiyuan County in Sichuan Province called Pocheng?

Weiyuan, also known as Pocheng, originated from Popo Hotel in the corner of Yantang outside the south gate. Once upon a time, there was a very big Castanopsis fargesii tree at the corner of the weir pond, which covered half the sky like a giant umbrella. In summer, the leaves are rustling and the cool breeze is blowing gently, and all passers-by stop in the shade to enjoy the cool. An old woman took a good look at this place and set up a thatched shed under the tree to do catering business. Soon, the old woman's son died, and her daughter-in-law was young and widowed. She wanted to remarry, but she was afraid to say it. In addition, she was very tired from running a restaurant in the dark and had nowhere to say anything. She had to secretly grieve and cried her eyes out. Because there was nowhere to vent her grievances, she had to deliberately put the "Maoertou" full and tightly when she was scooping food for customers, thinking that the restaurant would be closed only if the business was eroded! I didn't know that the more solid she added, the more people came to eat, and the business not only didn't lose money, but made money. Mother-in-law said that her daughter-in-law is capable and can do business. Daughter-in-law says that her mother-in-law is virtuous, and she will greet the guests before they come to the door. The mother-in-law and daughter-in-law talked and laughed, and the more they worked, the more their business became more and more popular, and the thatched house became a new tile house. Kannika nimtragol also have no intention to go, stay and do business. When everyone saw that the mother-in-law shop made money, they all went there to set up sheds to do business, one by one, and connected them into a street. Seeing that there are more shops, the mother-in-law and daughter-in-law are afraid of fewer customers, so they wash the dishes, chopsticks, tables and stools clean, and guests always greet them with smiles when they come, so there is always an endless stream of people coming to the store to eat. The stores opened by other men are dwarfed and business is depressed. The business of mother-in-law shop is always better than any other shop, and people want to find a reason. One day, a Mr. Feng Shui came. He looked around with a compass and said, "This place is on the Kun Gua, so it is better for a woman to open a shop than a man!" At that time, people believed it, and all the shops changed owners to women. Even if the shops were still opened by men, they were also dressed in women's clothes, and they were also named "mother-in-law shops". One year, the emperor came here incognito and wanted to stay in the "mother-in-law shop". But when he got there, the signs of "mother-in-law shop" hung all over the street, and the shopkeepers all ran out and said, "We are the authentic mother-in-law shop!" The emperor was confused by the noise and quickly said, "OK, don't argue, everyone is a mother-in-law shop!" " When people know that he is the emperor, they all want to get a seal for good luck. The emperor said, "It's unfair that there are only male states and no female counties in the world. The mothers-in-law here are very capable, so it's better to call them' Pocheng'." Since then, Weiyuan County has had the nickname "Pocheng". Later, the streets in the county town were also controlled by the pattern of "Kun Gua"
