August of the lunar calendar is the second month of autumn, so it is called "Mid-Autumn", while August 15th of the lunar calendar is just half of autumn, so it is called "Mid-Autumn Festival". At first, this day was designated as a festival for the ancient emperors to sacrifice the moon, and it gradually evolved into the Mid-Autumn Festival.

The Mid-Autumn Festival originated from the worship of celestial phenomena and evolved from the worship of the moon in autumn in ancient times. At first, the festival of "Sacrificing the Moon" was held on the day of "Autumn Equinox" in the 24th solar term of the Ganzhi calendar, and later it was transferred to August 15th of the summer calendar (lunar calendar). In some places, the Mid-Autumn Festival was set on August 16th of the summer calendar. Since ancient times, Mid-Autumn Festival has had folk customs such as offering sacrifices to the moon, enjoying the moon, eating moon cakes, playing with lanterns, enjoying osmanthus flowers, drinking osmanthus wine, etc., which have spread to this day and lasted for a long time.

In the early days, people didn't call moon cakes "moon cakes". There were many names, such as "Hu cakes" mentioned by Li Yuan, as well as "small cakes", "moon group", "palace cakes", "golden cakes" (Song Dynasty) and "moon cakes" (Yuan Dynasty). In the Tang Dynasty, the most popular name was naturally Hu Bing. In the past, the Han people referred to the Huns, Xianbei, Di, Qiang, Tubo, Turkic and other nomadic peoples living in the north and west of China as "conference semifinals". Hu people's daily bread is called "Hu cake" by Han people. This kind of cake is round, filled with sugar and covered with nuts. It's delicious.

Then, how did Hu Bing change its name to moon cake? This is related to Yang Yuhuan-Yang Guifei, one of the four beauties in China.

Yang Yuhuan, formerly known as Yang Furong, was originally the eighteenth son of Li Longji in the Tang Dynasty and the concubine of Li Mao, the life king. Yang Meiren is familiar with temperament, can sing and dance well, and the most important thing is that she is outstanding in appearance. If she is really out of the water, men will not be tempted. Li Longji, a lecherous woman, got her 27-year-old daughter-in-law into her harem, conferring her the title of imperial concubine, and she was pampered by thousands. One Mid-Autumn Festival, Li Longji and Yang Guifei ate Hu cakes together to enjoy the moon. Li Longji, who is romantic, pretends to be elegant. She thinks that Hu Bing is not nice and wants to change her name. But what should I call it? I can't think of it at the moment. Yang Guifei looked up, and there was a full moon hanging in the air at that time, just like this round Hu cake, so she blurted out-moon cake. Hearing this, the Li Longji repeatedly clap your hands. A "moon cake", which was called out.

May you also bring your own light, neck and neck with the Mid-Autumn Moon.

The warmest lamp tonight is probably the moonlight on the way home.
