Behind Wan-shan Temple in Xialiao, Kouhu Township, lie more than three hundred small mounds that hold the ashes of ancestors who perished in a tsunami 161 years ago. Locals call the site the “Wan-shan-tong-gui Graveyard,” and it has been listed as a Yunlin County historic monument. Nearby residents say that whenever they try to count the exact number of graves, no two people ever arrive at the same figure—a curious phenomenon. Every year on the 7th and 8th days of the sixth lunar month, Wan-shan Temple at the old Jinhu Harbor in Hanziliao, Kouhu Township, and the Jinhu Wan-shan-ye Temple in the Jinhu area jointly hold grand ceremonies to commemorate the victims. These rites have evolved into the “Pulling the Water (Chariot Storehouse)” ritual, a rare Taiwanese folk ceremony for victims of a maritime disaster.
