What is Yang Hongri?

Old customs and superstitions began on the thirteenth day of the first lunar month, and then two days in advance every month will be Pepsi taboo day. According to legend, it began with Yang, a warlock in the Song Dynasty, because it was called Yang Gongbi.

A long time ago, there was an old man named Yang. People call him Yang Gong. The young man has thirteen sons, and thirteen sons are as rich as wolves. It can be said that some people need money and wealth. Yang Gong was born a little eccentric. One day, I was very happy. I chatted with a person there and said, "I haven't given birth to a son for a month. I can still give birth to a son to celebrate the New Year."

Immortals are everywhere, but mortals should not talk too crazy. A fairy passing by heard Yang Gong's crazy words. This god reported to the Jade Emperor, who was furious and ordered him to accept a son every month. Since the 13th day of the first month, Yang Gong's son has to leave once a month. Advance two days a month, the thirteenth day of the first month, the eleventh day of February, and the ninth day of March, and advance downward in turn. This year happens to be leap July, so Yang Gong's two sons were accepted in July. The dates are July 1st and 29th, so this year is thirteen months. Yang Gong's thirteen sons naturally left none. By the end of the year, naturally no one will spend the New Year with Yang Gong. Later, people called the day when their son died Yang. These days are very poisonous, so I can't go out. However, it doesn't matter that people go out every day now, but if you want to choose a day, you'd better not choose these days.
