For example, in ancient times, there was the saying of "offering sacrifices to the sun in spring and the moon in autumn". Now the Mid Autumn Festival comes from the traditional "Moon Festival". According to textual research, the original "Moon Festival" was set on the "autumn equinox", but because this day is different every year in August of the lunar calendar, there may not be a full moon. Sacrificing the moon without the moon is a great evil. Therefore, the "Moon Festival" was later adjusted from the "autumnal equinox" to the Mid Autumn Festival. According to historical records, as early as the Zhou Dynasty, ancient emperors had the customs of offering sacrifices to the sun at the spring equinox, to the earth at the summer solstice, to the moon at the autumn equinox and to the heaven at the winter solstice. The places of sacrifice are called the altar of the sun, the altar of the earth, the temple of the moon and the temple of heaven. It is located in four directions of southeast and northwest. The moon altar in Beijing is the place where the emperors of the Ming and Qing Dynasties sacrificed the moon. According to the book of rites, "the son of heaven, the sun in spring, the moon in autumn, the sun in the morning, the moon in the evening." the night of the moon here refers to the night sacrifice to the moon. This custom was not only pursued by the court and the upper nobility, but also gradually affected the people with the development of society. According to the "autumn dew in spring and autumn · Yin and Yang in and out part I and part II": "the autumnal equinox is accompanied by Yin and Yang, so the cold and heat are even day and night."
