Qing Shui Zu Shi, also known as Chó͘-su-kong in Hokkien, was a Zen Buddhist monk during the Northern Song from An Xi County, Quanzhou. He was said to have supernatural powers that bringing rain to save people during drought, curing sickness with herbs and building bridges to ease villagers. In reverence, the villagers built shrines for him and hence became a famous Deity in Chinese folk religion. The Birthday of Qing Shui Zu Shi is on Chinese Lunar calendar: Month 1 Day 6, Month 6 Day 6 and Month 11 Day 6.
Hock Hin Keong is better known as the Ban Kah Lan Snake Temple. Located in the vicinity of a disembarkation point in Sungei Kluang called Pengkalan, it is also called Cheng Hoon Gam. It originally started in the period of 1820’s-1830’ as a private place of worship of an An Xi monk devoted to Qing Shui Zu Shi. The worship of Qing Shui Zu Shi became gradually popular in about 1836, and was the place of origin from where Cheng Hoe Seah obtained its incense. The Chneah Hoay or Flame-watching ritual at mid-night on the eve of the Qing Shui Zu Shi Birthday on the 6th day of the 1st moon of the Chinese calendar has thus been continued and propagated until today. The Flame-watching ritual also becomes the annual prediction of Penang economy.
