In Penghu Town, Yongchun, Fujian, the folds of the mountains hide secrets that are older than the genealogy - the incense of Wuji Rock cannot suppress the coldness of Baizhang Rock, the century-old banyan tree will sing on rainy nights, and the whirlpool at the bottom of the reservoir always swallows up lonely souls in the middle of the month.
Xie Ping, a part-time job worker at the town health center, is gifted with a pair of "yin and yang tricks", and his words are full of enthusiasm in southern Fujian slang: "Come to the north, even ghosts in this world have to practice martial arts!" He carries an ancestral bronze lancet on his waist. Glutinous rice sachets soaked with cinnabar are specially designed to treat "ignorant" people in the spiritual world - such as the cockroach spirit that traps hikers in the "ghost wall" and eats human brains, or the opium spirit that has been hanging on the beam of an ancient house for thirty years and specializes in sucking the yang energy of girls.
