The Yin and Yang Account of Late Night Bookstore

Qian Qi, an antique restorer, took over the late-night bookstore left by his grandfather and accidentally discovered the secret of "Yin Yang Account" - this account can connect Yin and Yang, and welcome special "customers" with obsession every night. The ghost of an embroiderer wearing a cheongsam comes looking for stolen wedding dress embroidery patterns, but it actually hides the truth about a murder during the Republic of China; the ghost of a senior high school student is trapped in the old teaching assistant because the strange red cross on the test paper was not drawn by the teacher. Qian Qi was forced to transform into a "yin and yang accountant". Every time an incident was solved, fragments of his grandfather's handwriting would appear in the account book. He gradually discovers that these seemingly independent supernatural events are all related to the "disappearance" of his grandfather twenty years ago - in order to save a mother in labor, his grandfather modified the account books without authorization and reversed life and death, causing a disorder of yin and yang. With the help of the civet cat Aman, Qian Qi solved the unit's mystery (such as the Internet celebrity anchor being entangled by a "shadow double" and the bronze mirror in the antique shop revealing the true face of the deceased) while piecing together the main truth. When the last page of the account book was filled, he faced a choice: follow the rules of the underworld and erase the traces of his grandfather, or bear the price to continue this redemption that spans Yin and Yang.
