When Yeh Chih-sheng steps aboard Taiwan Coast Guard vessel CG1005 in the choppy waters of the Taiwan Strait, he brings more than his uniform and orders: he also has temple charms blessed by the gods ​revered by fishers for protection at sea. Yeh is first mate of the 2,400-ton ship based ‌in Taiwan’s ‌Penghu islands, and part of Taipei’s maritime front line as China asserts its claim ​of sovereignty over the democratically governed island.

Off duty, he is an assistant priest, or ”sio-huat” in Taiwanese, at a Penghu temple devoted to the Five Lords — guardian deities long worshipped by coastal communities ⁠for safe seas and protection from plague. Yeh has served the gods since primary school, helping spirit mediums during rituals ⁠in which deities are believed to descend from the heavens and deliver instructions.

“The Coast Guard is a tangible backing people can see,” Yeh said. “The Five Lords are ​a spiritual anchor in people’s hearts. Both ⁠help bring fishermen and ordinary people a sense of reassurance.”
