When was the earliest Mid-Autumn Festival?

Mid-Autumn Festival can be traced back to the worship of celestial phenomena in ancient times. For the moon that shines high in the sky every night, and is constantly in surplus and deficiency with the change of time, primitive humans feel very strange, and the worship of the moon has emerged. According to textual research, before the birth of Mid-Autumn Festival, our ancestors often sacrificed the moon on the equinox, also known as the "Festival of Sacrificing the Moon", and later changed it to August 15th. It was not until the Han Dynasty that the name "Mid-Autumn Festival" appeared in the literature, and the Mid-Autumn Festival gradually spread and popularized.

Mid-Autumn Festival, as a high-level traditional festival in China, originated from ancient people's worship and sacrifice to the moon. After thousands of years of development, the name, date and content of Mid-Autumn Festival have been gradually established, and it has also changed from a primitive sacrificial activity to a grand festival symbolizing reunion. As the saying goes, "The moon is now full of the sea, and the horizon at this time is * * *". When the moon rises on the night of Mid-Autumn Festival, reunion becomes the hope of China people at home and abroad. This invisible bond is also the most important significance of Mid-Autumn Festival to us.
