[The main altar with Koxinga in the center. This statue resembles the one in the Cheng Family Temple in Tainan, both clean-shaven. The one in 延平郡王祠, also in Tainan, is based on a portrait with a black beard suggesting it was done during a mourning period. In Hokkien custom, sons do not shave when their parents passed. ]
The full name of Khye-Sian-Ong-Tua-Pek-Kong temple in Jelutong日落洞, Penang檳榔嶼, is 開山王大伯公廟. We already know who 開山王 is [Koxinga], but who is 大伯公 (the bearded one on the right), and why a third deity (the child on the left), apparently NaZa哪吒, is also on the altar?
