There are several versions of the legend about the origin of moon cakes: (1) It is said that this version is the most authentic: according to legend, in ancient China, emperors had the ritual of offering sacrifices to the sun in spring and the moon in autumn. In the folk, every Mid-Autumn Festival in August, there are also customs about Yue Bai or offering sacrifices to the moon. The famous proverb "The moon is full on August 15th, and the moon cakes in Mid-Autumn Festival are sweet and fragrant" tells the custom of urban and rural people eating moon cakes on Mid-Autumn Festival night. At first, mooncakes were used as sacrifices to the moon god. Later, people gradually regarded the Mid-Autumn Festival as a symbol of family reunion, and gradually mooncakes became holiday gifts. Moon cakes, originally originated from the Tang Dynasty army Zhujie food. During Tang Gaozu's reign, General Li Jing conquered the Huns and returned home in triumph on August 15th. At that time, Turpan people who were doing business presented cakes to the emperor of the Tang Dynasty. Gao Zu Li Yuan took the gorgeous cake box, took out the round cakes, smiled at the bright moon in the sky and said, "We should invite toads with Hu cakes." After that, share the cake with the ministers. The word "moon cake" has been used in Wu Zimu's book Menglianglu in the Southern Song Dynasty, but the description of tasting the moon and eating moon cakes in the Mid-Autumn Festival was recorded in the West Lake Touring Society in the Ming Dynasty: "August 15th is called the Mid-Autumn Festival, and the people take the meaning of reunion with moon cakes". By the Qing Dynasty, there were more records about moon cakes, and the production became more and more elaborate. Mooncakes symbolize reunion and are a must-eat item in Mid-Autumn Festival. On the night of the festival, people also like to eat some reunion fruits such as watermelons and fruits, and wish their families a happy, sweet and safe life. (2) This version is vague, which has some connection with the other two versions: the custom of eating moon cakes in the Mid-Autumn Festival began in the Tang Dynasty. According to "Experiences in Luozhong", Tang Xizong eats moon cakes on Mid-Autumn Festival, which is very delicious. He heard that all the new courses were held in Qujiang, so he ordered the imperial kitchen to give them mooncakes wrapped in HongLing, which was the first record of mooncakes. By the Song Dynasty, mooncakes had various colors, such as lotus leaf, golden flower and hibiscus. Su Dongpo once praised mooncakes, saying, "Small cakes are like chewing the moon, with crispness and flesh in them. Crisp is ghee and caramel is caramel. In the Yuan Dynasty, according to legend, before the Mid-Autumn Festival, Zhang Shicheng, a native of Taizhou, secretly connected in series, and hid a note that said "On August 15th, everyone will join hands to destroy the Yuan Dynasty" in a moon cake, and sent it to each other and contacted each other. On the night of Mid-Autumn Festival, every family ate moon cakes, seized kitchen knives in succession, rebelled against the rulers of the Yuan Dynasty, and since then, the wind of eating moon cakes has flourished to commemorate this festival. In the Ming dynasty, the wind of offering sacrifices to the moon was very popular. Emperor Shizong of Ming Dynasty also sent officials to build the Xiyue Temple, which is now Beijing Yuetan Park. This is a special place for the imperial court to worship the moon. Every three years, the emperor will personally sacrifice the "God of Night Light", and in the rest of the year, he will send officials from civil and military departments to perform the sacrifice. At the same time, the Mid-Autumn Festival also held a moon-offering activity in the Imperial Palace. (3) This version is the most widely circulated among the people: it is said that eating moon cakes in the Mid-Autumn Festival began in the Yuan Dynasty. At that time, the broad masses of people in the Central Plains could not bear the cruel rule of the ruling class in the Yuan Dynasty and rebelled against the Yuan Dynasty. Zhu Yuanzhang joined forces with various resistance forces to prepare for the uprising. However, the officers and men of the court searched very closely and it was very difficult to pass on the news. Strategist Liu Bowen came up with a plan and ordered his subordinates to hide the note containing the "August 15th night uprising" into the cake, and then sent someone to send it to the uprising troops in various places separately to inform them to respond to the uprising on August 15th night. On the day of the uprising, all the rebels responded together, such as single spark can start a prairie fire. Soon, Xu Da captured the Yuan Dynasty and the uprising was successful. When the news came, Zhu Yuanzhang was so happy that he quickly gave a message that all the soldiers would have fun with the people in the upcoming Mid-Autumn Festival, and he would give the "moon cakes" that were sent in secret when he started fighting that year as seasonal cakes to his ministers. Since then, the production of "moon cakes" has become more and more elaborate, with more varieties, such as discs, and has become a good gift. After the Mid-Autumn Festival, the custom of eating moon cakes spread among the people. Modern people eat moon cakes with the meaning of reunion, hoping that eating moon cakes can bring happiness and happiness to their families, so the names of moon cakes are all based on this direction, such as the rainbow rose moon cakes of Holiland.
