 The Chinese believe that on the 15th day of the seventh lunar month, the gates of underworld would open and the dead souls whom without any descendants to conduct ancestral worship for them would be allowed to roam in the living realm to receive food and offerings.The Chinese would placate the 'hungry ghosts' by organizing big worship celebration that include religious rituals, burning incense, making food offerings and performing Chinese opera or getai on makeshift stages.At the end of the month-long festival, a giant effigy of Da Shi Ye (大士爷) who is maintaining the law and order of the 'hungry ghosts' will be send off and burned.
