The 15th day of the seventh lunar month every year is the "Obon Festival", also known as the "Hungry Ghost Festival". In some places and states, it is commonly known as "Ghost Festival" and "Shigu". It is originally a Buddhist ritual in India. In the early 19th century, Buddhists held the "Ollambana" in order to honor their ancestors; the "Ollambana Sutra" in the Buddhist scriptures encouraged Buddhist disciples to practice filial piety, which was in line with the Chinese common belief of remembering the ancestors and mourning the distant past, so it became more and more popular. The story of Mulian rescuing his mother from misfortune is widely circulated among the people:

"The monk with Mulian has great magical power. His mother fell into the realm of hungry ghosts, and food turned into flames when she entered the mouth. The hunger and suffering were too great. Mulian could not help To save his mother from misfortune, he asked the Buddha for advice and taught him how to make the Ullambana Sutra on the 15th day of the seventh month to save his mother."

China followed this example from the Liang Dynasty. Together they become the Ghost Festival. However, later on, in addition to setting up fasting for monks, activities such as worshiping, repenting, and setting off flames were also added.

On this day, the Master's Seat and Shigu Terrace were set up in front of Jiekou Village in advance. In front of the mage's seat is the Ksitigarbha Bodhisattva who has saved the ghosts of "hell", and below is a plate of peaches and rice. There are three spiritual tablets and soul-calling flags standing on Shi Gutai. After noon, every household placed whole pigs, whole sheep, chickens, ducks, geese and all kinds of cakes, fruits, melons, etc. on Shigutai. The person in charge put a handful of triangular paper flags in blue, red, green and other colors on each sacrifice, and wrote words such as "Bon Lan Festival" and "Ganlu Gate Opens". The ceremony began with a burst of solemn temple music. Immediately afterwards, the mage rang the bell and led the monks to recite various mantras and mantras. Then serve, scatter a plate of noodles with peaches and rice in all directions, repeat three times. This ceremony is called "flaming mouth".

At night, every household will burn incense at the door of their house and put the incense on the ground. The more the better, symbolizing a good harvest. This is called "cloth field". In some places, water lanterns are released. The so-called water lantern is a lamp tied on a small wooden board. Most of them are made of colored paper into the shape of a lotus, which is called a "flood and drought lantern". According to traditional saying, water lanterns are used to lead the way for ghosts who have died unjustly. When the light goes out, the water lantern completes its task of luring the innocent souls across the Naihe Bridge. The shops were also closed that day, leaving the streets to ghosts. In the middle of the street, an incense table is placed every 100 steps, with fresh melons and fruits and a kind of "ghost buns" on it. There was a Taoist priest behind the table singing ghost-sacrifice songs that no one could understand. This kind of ceremony is called "Shi Geer".

The Shangyuan Festival is the human Lantern Festival. People decorate the Lantern Festival with lanterns and colorful decorations. "Zhongyuan" comes from Shangyuan. People believe that the Ghost Festival is a ghost festival, and lanterns should be put up to celebrate the festival for ghosts. However, humans and ghosts are different, so the lighting of lanterns in Zhongyuan is different from the lighting of lanterns in Shangyuan. Humans are yang, ghosts are yin; land is yang, water is yin. The mysterious darkness under the water reminds people of the legendary hell, where ghosts sink. Therefore, the lanterns were lit in the Shangyuan on land, and the lanterns in the Zhongyuan were lit in the water
