Who does the traditional Chinese festival of Mid-Autumn Festival commemorate?

According to historical records, the term "Mid-Autumn Festival" first appeared in the book of "Zhou Li", and every Mid-Autumn Festival in the Zhou Dynasty was held on the night of Mid-Autumn Festival to welcome the cold and offer sacrifices to the moon. Many people usually say that the Mid-Autumn Festival originated from the story of Chang'e running to the moon. According to the history books, "In the past, Chang'e took the medicine of immortality from the Queen Mother of the West and ran to the moon as the moon spirit." The price Chang'e paid for this act was to be punished with hard labor and not be able to return to earth for the rest of her life. Li Bai was very sad about this and wrote the following poem: "The white rabbit pounds medicine in the fall and then in the spring, who is the neighbor of the female Chang'e who lives alone?" Although Chang'e herself feels the good of the Moon Palace, but also can not bear the loneliness, in the 15th of August every year when the moon is full and the night is clear, return to the earth to reunite with her husband, but in the morning before it must return to the Moon Palace. Whenever the Mid-Autumn Festival comes around, people in the future generations would like to go to the moon and get together with Chang'e, and they also hope that Chang'e will come down to the earth to have a glimpse of her face. Therefore, many people burned incense to worship the moon, praying for "men wishing to step into the Toad Palace early and climb up to the immortal laurel ...... Women wish to look like Chang'e and be as round as the moon." Year after year, people celebrate this day as a festival. Some people believe that the Mid-Autumn Festival only became a regular festival in the early Tang Dynasty. The Book of the Tang Dynasty (唐书-太宗记) records that the Mid-Autumn Festival was held on the fifteenth day of the eighth month. The Mid-Autumn Festival was started by Emperor Ming Huang of the Tang Dynasty who enjoyed the moon. The Tang Dynasty "Kaiyuan Legacy" book records: the Mid-Autumn Festival night, Tang Ming Huang and Yang Guifei in the moon swim play, swim to the rise, the two logged into the Moon Palace, Tang Ming Huang also learned in the Moon Palace half of the "Nishang Yuyi song", and later supplemented the integrity of the work of heirlooms. Tang Ming Huang can not forget this trip to the Moon Palace, every year to this moment, necessary to enjoy the moon. Hundreds of people also come to follow suit, when the moon is full to get together and enjoy the beauty of the world. Over time, it became a tradition that has been passed down. In the Tang Dynasty, the Mid-Autumn Moon Festival, playing with the moon is quite popular. And it has been suggested that the Mid-Autumn Festival was originally the anniversary of an uprising that overthrew the rule of the Yuan Dynasty. At the end of the Yuan Dynasty, the common people could not stand the rule of the government, so during the Mid-Autumn Festival, they hid notes written with "Kill the Tartars, destroy the Yuan Dynasty; on August 15, every family will do it together" inside small round cakes made of chrome and passed them to each other. On the night of August 15, every family took action to overthrow the Yuan Dynasty. Later, every Mid-Autumn Festival, we ate mooncakes to commemorate this historic victory. By the time of the Ming and Qing Dynasties, the Mid-Autumn Festival was on a par with New Year's Day as one of the major festivals in China, and became the second largest traditional festival in China after the Spring Festival.
