Annually, from January 1 to 15, the temple receives numerous visitors, such as those whose prayers were answered returning to thank the immortal. Wong Tai Sin's birthday on the 23rd day of the 8th lunar month, and the Chinese New Year holidays are the busiest times for the temple.
On the Chinese New Year's Eve, thousands of worshippers wait outside the temple before midnight and rush in to the main altar to offer Wong Tai Sin their glowing incense sticks when the year comes. As the tradition goes, the earlier they offer the incense, the better luck they will have that year.
The act of "Kau Cim" at Wong Tai Sin.
Most of the visitors come to the temple in search for a spiritual answer via a practice called Kau Cim. They light incense sticks, kneel before the main altar, make a wish, and shake a bamboo cylinder containing fortune sticks until a stick falls out. This stick is exchanged for a piece of paper bearing the same number, and then the soothsayer will interpret the fortune on the paper for the worshiper. Often the same piece of fortune is taken to multiple booths for verification purposes. Some booths offer palm reading service.
Recently, Taoist weddings have been performed here.
The temple is open from 7:00am to 5:30pm throughout the year, and runs overnight in the Lunar New Year Eve. It is currently administrated by Sik Sik Yuen, a Taoist organization in Hong Kong.
