The origin of Mid-Autumn Festival is a short 30 words:

The origin of Mid-Autumn Festival is closely related to the moon, which is a relic of ancient custom of worshipping celestial phenomena and respecting the moon. In traditional culture, the moon and the sun are the same, and these two alternate celestial bodies become the objects of ancestor worship. In the twenty-four solar terms, the "autumnal equinox" season is an ancient "moon festival", while the Mid-Autumn Festival comes from the traditional "autumnal equinox festival".

According to research, "Mid-Autumn Festival" was originally set on the day of autumnal equinox in the twenty-four solar terms of the Ganzhi calendar. However, due to the integration of calendars in historical development, the lunar calendar (summer calendar) was used, and then the Mid-Autumn Festival was transferred from the 24 solar terms "autumnal equinox" to August 15 in the summer calendar. Mid-Autumn Festival is a synthesis of autumn seasonal customs, most of which have ancient origins.

Customs of Mid-Autumn Festival:

In some places in Guangdong, there is an interesting traditional custom of Mid-Autumn Festival, which is called "Tree Mid-Autumn Festival". The tree is also vertical, which means that the lamp stands high, so it is also called "vertical Mid-Autumn Festival". With the help of parents, children make rabbit lanterns, carambola lanterns or square lanterns out of bamboo paper, hang them horizontally on short poles, and then stand on high poles, shining with colorful lights, adding another scene to the Mid-Autumn Festival.

Children often compete with each other to see who stands tall, much taller and has the most exquisite lighting. At night, the lights in the city are like stars, competing with the bright moon in the sky to celebrate the Mid-Autumn Festival.
