1. Legend from the Goddess Chang'e flying to the moon Long ago, there were ten suns in the sky, which scorched the crops and made the people extremely hot. There was a man named Yi who bent his bow and took an arrow and shot down nine suns in one breath. After she became a hero, she married a girl named Chang 'e as her wife. They loved each other and lived a happy life. Chang 'e is beautiful, hardworking and kind-hearted. She often distributes the wild animals she has hunted to the villagers. One day, a Taoist priest in Yi Lu Yu said, "You have made great contributions to the people. I'll give you a pack of magic medicine. If you eat half a pack, you will live forever. If you eat it all, you will become immortal and ascend to heaven. " Yi took the magic medicine home and gave it to Chang 'e for safekeeping. He is going to find a suitable time to share this bag of magic medicine with Chang 'e, and the husband and wife will live forever and never part. Feng Meng, a disciple of Yi, came up with a bad idea when he knew that there was a magic medicine hidden in Yi's house. On August 15th of this year, Yi took his disciples out hunting. In the evening, Feng Meng sneaked back alone and forced Chang 'e to hand over the magic medicine. In order not to let the magic medicine fall into Feng Meng's hands, Chang 'e had to open the medicine bag and eat all the magic medicine. Suddenly, Chang 'e felt that her body was as light as a swallow, drifting to the moon and living in the Guanghan Palace. When you got home and heard about it, you hurried out the door, but it was too late! I saw the shadow of Chang 'e on the round moon. The villagers said that Chang 'e would come back and advised you to wait patiently. On August 15th of the following year, Yi missed Chang 'e, so she took out Chang 'e's favorite fruits, put them in the yard, and made round moon cakes to show her reunion and hope that Chang 'e would come back. Year after year, Chang 'e still didn't come back. Slowly, people have the habit of celebrating the holidays. Every August 15th, food such as moon cakes and fruits should be prepared. Second, the "Hu cake" originated in the early Tang Dynasty. During the Wude period in Tang Gaozu, the border guards invaded the territory. Excavate went to war and won a great victory. He triumphed in the Mid-Autumn Festival and celebrated all night inside and outside Chang 'an. Sometimes Tubo people offered cakes to celebrate their victory, and Gaozu took out the round cakes and smiled at Mingyue, saying, "We should invite toads with Hu cakes." Later, it was given to the ministers, thus forming the custom of eating moon cakes in the Mid-Autumn Festival. Third, it originated from Tang Minghuang's fantasy visit to the Moon Palace. According to legend, on a mid-autumn night, Li Longji, Emperor of the Tang Dynasty, was enjoying the moon in the palace. Luo Gongyuan, a Taoist priest beside him, changed his magic, threw his cane into the sky and turned it into a long bridge, inviting Xuanzong to visit the moon palace with him. When they walked across the long bridge, a palace suddenly appeared in front of them, and the book read "The House of Wide Cold and Clear Deficiency". In the palace, Chang 'e ordered the maids to bring delicious fairy cakes for the guests to taste. When he returned to earth, Emperor Tang Ming ordered people to copy it as seen in the Moon Palace. Since then, there has been a "moon cake" in the shape of a full moon. Fourth, it originated from the news of the uprising. According to legend, during the Yuan Dynasty, the broad masses of the people in the Central Plains could not bear the cruel rule of the Mongols and rebelled against the Yuan Dynasty. Zhu Yuanzhang wanted to unite the resistance forces, but the Yuan soldiers searched closely and could not pass on the news. Liu Bowen came up with a plan, ordered Wang Zhaoguang to make cakes, and hid a note with the words "August 15th Uprising" in the cakes. Then send them to the uprising troops in various places separately, and inform them to respond to the uprising on the evening of August 15 and overthrow the Yuan Dynasty. To commemorate the merits of cakes, the custom of eating moon cakes in Mid-Autumn Festival has been handed down. In North China and East China, there is still a saying that "Da Zi was killed on August 15th". In fact, moon cakes appeared in the Tang Dynasty, and became more prosperous in the Song Dynasty. It is the most important item when worshipping the moon during the Mid-Autumn Festival, and it is shared by the whole family after the offering. Because moon cakes symbolize reunion, they are called "reunion cakes" in some places. "Yanjing Year-old Moon Cake" contains: "Moon cakes for the moon are everywhere, and the largest ones are more than feet long, with the shape of a moon toad and rabbit painted on them. Those who eat after the sacrifice, and those who eat until New Year's Eve. " Su Dongpo's poem says: "A small cake is like chewing the moon, and it has crispness and pulp in it." Yang Guangfu's Song Nan Cai Fu in Qing Dynasty wrote: "Moon cakes are filled with peach meat, and ice cream is made of sugar cream." It can be seen that since the Tang Dynasty, eating moon cakes in the Mid-Autumn Festival has become a custom and has been handed down. As for enjoying the moon, it is because the temperature is cool but not cold in the Mid-Autumn Festival, the sky is crisp and the moon is bright, which is the best season to play with the moon. Of course, it also contains a great part of the meaning of "sustenance", "missing" and "praying". The poems chanting the moon in Tang dynasty can be used as evidence.
