The Zhongyuan Festival, also known as Ullambana Festival among Buddhists, falls on the fifteenth day of the seventh lunar month, on Aug 17 this year.

Since ancient times, the Chinese have believed that the gates of hell open on that day and so people hold all kinds of activities to honor the ghosts. Therefore, the festival is also called the Ghost Festival.

There are two other festivals in China to honor departed spirits of ancestors: Qingming Festival (in spring) and the Chung Yeung Festival (in autumn). In both, living descendants pay homage to their deceased ancestors. Zhongyuan Festival is distinct from these, as the deceased are believed to visit the living.

Buddhist doctrine says that by offering articles on the festival day, deceased parents and relatives can be saved from bad situations in the after life. The Ullambana Festival of Buddhism has two meanings. One is to persuade people to provide for Buddhist monks. The other is to convince people to do more charitable deeds to release departed souls from sin and advocate family devotion.

The Ullambana Festival is related to the legend of Mulian Saves His Mother.

It is said that after going through innumerable trials and hardships in the nether world, Mulian finally saw his mother, only to find her being tortured by a group of hungry ghosts. Mulian wanted to send his mother rice and dishes with an earthen bowl, but the food was snatched by the hungry ghosts. Mulian had no choice but to ask Buddha for help. Moved by his filial piety, Buddha presented Mulian with the Ullambana Sutra and told him to participate in an Ullambana Fast on July 15 of the lunar calendar. On that day, food of various kinds as well as five fruits -- peaches, plums, apricots, chestnuts and dates -- should be provided to all Buddhist monks. Under the instruction of the Ullambana Sutra, Mulian filled the Ullambana vessel with fruits and vegetarian food to offer a sacrifice to his mother on July 15. His starving mother finally got the food. To show his gratitude to the Buddha, Mulian held an almsgiving activity every year to release the hungry ghosts from the disaster of being hanged by their feet.

The day has become a festival to honor departed ancestors, relatives and friends.
