Basic introduction:

My Years as a Teacher of Yin and Yang is a supernatural novel written by Cui Zouzhao. The protagonist Cui (whose father casually looked through Xinhua Dictionary, the first word on a page was invalid, and his mother disagreed, so it was changed to homophonic) accidentally drowned when he went out to sketch in an art class (in fact, his grandfather offended the well-trained "yellow leather" and unfortunately soaked the amulet given to him by Teacher Liu while the grievances were still unresolved, and was unfortunately killed). After his death, he met Uncle Jiu, a descendant of Sanqing in Yin Shi, and taught him the charm of Sanqing cloth and the method of returning to the soul. After an arduous resurrection, in order to fulfill the responsibility entrusted by the master as a teacher of Yin and Yang of the White School and eliminate the monsters that affect human harmony ...

In the job search after graduation, I hit a wall several times and was finally introduced to a fortune-telling hall called Fuzetang, where I worked under my boss Uncle Wen. Watching the store during the day and "guarding the road" at night, he used his unskilled Taoist skills to resolve grievances again and again. In an action, I met Yi Xinxing, a disciple of Bai Dao, and found that he was a descendant of Sanqing Qimen. After living together, the two men shared the same temper and forged a brotherly friendship through life and death. In modern society, in the materialistic and stubborn life, who is the most terrible, ghosts or people? The protagonist's mind is lost, and there is a big conspiracy waiting for them, a trap that wants to go against the sky.
