According to Taoism (Daoism), the Jade Emperor lives in the 33rd heaven and governs 33 heavens; so he is the king of heavens. Jade Emperor is a vegetarian. To celebrate his birthday, Chinese prepare three bundles of long noodle, three tea cup with green tea, five different kinds of fruit and six different kinds of dry vegetables to worship Jade Emperor. But people also prepare five animal sacrifices, different sweet cakes and turtle cake (turtle is a symbol of longevity) on a different table for Jade Emperor's guardian soldiers.
To show the sincerity, many people take bath on the 8th lunar night, then wait for the first minute of 8th lunar day to begin the ceremony with their clean body. After the ceremony, Chinese explode the firecrackers. That's why we can hear the scattered sound of fire crackers from midnight to sunrise. The temple of Jade Emperor will be crowded as the Chinese New Year day since the night of 8th lunar day for those people unable to hold the worship event at home. For the same purpose, Chinese always pray for better luck, safety, health, love or money, when they visit the temple.
