Why is the Ghost Festival in Guangfu on July 14 and in other places on July 15? The Ghost Festival mentioned here is the Mid-Autumn Festival.

There are four traditional ghost festivals in China: March 3rd, Tomb-Sweeping Day, July 15th and October 1st. Every year from July 1st, the Prince of Yan ordered the hell to be opened wide, so that the ghosts who were imprisoned in the hell all the year round could come out of the hell, get a short stroll and enjoy human blood. Therefore, people call July a ghost month, and think it is an unlucky month, neither getting married nor moving.

The custom of Halloween is more complicated. In some places, it is on the 14th, and in some places it is on the 15th, even on the 13th and 12th. In some places, before the Mid-Autumn Festival in July 15, an auspicious day is chosen to worship the "family immortals" and ancestral graves, so it will be chosen on 13 or 14.

Therefore, customs vary from place to place, but at present it is generally set on July 15, because according to the Taoist worldview, it is customary to call the first month of the year 15 as "Tianguan" (the first half of the year) and "Shangyuan Festival"; In the second half of the year, July 15th, the local official festival, was called "Mid-Autumn Festival". Because the earth contains water, water acts on the earth, so1October 15 in the second half of each year is "Xiayuan Festival". These three elements, namely, upper, middle and lower elements, constitute a systematic understanding of the trinity world of Taoism.
