The main deity of Yuk Hui Temple is
Pak Tai, alternatively known as Yuen Tin Sheung Tai (), the Supreme Emperor of the Northern Heaven or the Mysterious Heaven. In Taoist mythology, he was once a prince of the
Shang dynasty, and then appointed by
Jade Emperor to fight the Demon King during the fall of the dynasty. He triumphed in the combat even though the Demon King conjured out a grey tortoise and a gigantic serpent for help. After this victory, Pak Tai was awarded the title of Yuen Tin Sheung Tai and is worshipped for his power, courage and devotion. The portrays of the tortoise and the snake under his feet symbolize that the good always prevails against the evil The temple also houses
Guanyin (Goddess of Mercy),
Tai Sui (the Sixty Gods of Time),
The old man under the moon (the God of Matchmaking) and
Tu Di Gong (a local earth god). Local residents and the fishing folks around the waters of the island are the major worshippers of the temple. Islanders would come to the temple during various festivals to pray for blessing or to present their gratitude, especially fishermen. They would come to invoke for an auspicious date and a great catch before setting sail and to thank for Pak Tai's blessing after their return. The two busiest times of the temple during the year are: • the Pak Tai Festival on the 3rd day of the 3rd
Lunar Month; • the Bun Festival- commonly known as the
Tai Ping Ching Chiu, the 8th day in the 4th Lunar Month. == Cultural and historical relics ==
