From the 1st day to the 9th day of the 9th month, the nine spirits of the North Star come to earth. Hence, during this period it is an official time for fasting for the composite god made up of nine former emperors who are supposed to be the mythological sons of the Queen of Heaven. It is notable that Kau Ong Yah control the health, longevity and wealth of those considered their devotees. Throughout the fasting period, people only eat vegetarian diet, wear charms and keep themselves clean from contact with unholy things. Devotees would jostle to pray in temples. Outside, yellow flags are raised, amulets are pasted on doors and altars. Chinese opera shows usually would be staged specially for the deities. On the 9th day an urn containing sandalwood representing the spirit of Kau Ong Yah would be handed over to the temple committee head for a ceremonial send-off in a decorated boat into the open sea. This will then mark the end of the festival.
