This festival of the seventh moon, as known as The Yulan Assembly( yulanhui ) or The passage of the Universal Salvaltion (Pudu), marks a transition for inhabitants of the world of shades from the status of threatening ghosts to that of stable spirit - for the time being anyway. During this period, all ghosts are released from the confines of the underworld to enjoy a month of freedom which culminates on the 15th day with a special ghost-feeding ritual. On the evening before the Ghost Festival, there is a lovely custom celebrated in areas in Taiwan and Hong Kong, of sending beautifully decorated paper boat and vater lanterns. On the 15th day, a large community celebration takes place in which Buddhist adn Taoist priest chant liturgies, perform rituals on an outdoor altar, and offer incense, paper clothes, and spirit money to the ghosts. Grandfather Seven and Grandfather Eight are two famous spirits who occupy a position in teh godly bureaucracy as patrolmen, reporting neighborhoos misconduct to the City God. In Chinese belief, the soul after death is judged according to what the person did during its lifetime. In many buddhist bible, there are a lot of chapters described the hell. If the person did a lot of bad things, it is generally believed that he would be punished to the 18th floor. That means it is hard to be man again.
