In the ancient customs of China, Shangyuan Festival (Lantern Festival), Zhongyuan Festival (Orchid Festival) and Xiayuan Festival (Shuiguan Festival) are collectively called Sanyuan.

1, Shangyuan Festival-15th day of the first month

Lantern Festival on the 15th day of the first lunar month, also known as Shangyuan Festival, Shangyuan Festival, Xiaoyuan Festival, Yuanxi Festival or Lantern Festival, is the first important festival after the Spring Festival, and it is also one of the traditional festivals in China, which is also a cultural circle of Chinese characters and overseas Chinese. The first month is the first month of the lunar calendar. The ancients called the night "Xiao", so the fifteenth day of the first full moon in a year is called the Lantern Festival.

Lantern Festival began in the Qin Dynasty more than 2,000 years ago. Emperor Wen of the Han Dynasty ordered the fifteenth day of the first month to be designated as the Lantern Festival. During the reign of Emperor Wu of the Han Dynasty, the ritual activities of "Taiyi God" were scheduled for the 15th day of the first month (Taiyi: the God who rules everything in the universe). When Sima Qian founded the "taichu calendar", he had identified the Lantern Festival as a major festival.

2. Mid-Autumn Festival-July 15th

July 15th is the Mid-Autumn Festival, which was originally a festival to offer sacrifices to ancestors and forgive sins of local officials. However, there is a saying among the people: on the first day of July, ghosts opened, and on the fourteenth day of July, ghosts strayed around, thinking that July was a ghost month. At night and in the wild, the yin is heavy, especially around the Mid-Autumn Festival, especially on the night of July 14th.

3. Next Yuan Festival-October 15th

October 15th of the lunar calendar is the traditional folk festival of China-Xiayuan Festival, also known as Xiayuan Day and Xiayuan Day. The origin of the next Yuan Festival is related to Taoism. There are three Taoist officials, namely, the celestial official, the local official, the water official and heavenly god blesses the people. The local official forgives sins and the water official relieves Eritrea.
