What did Fu Nian, a teacher of Yin and Yang, read when he buried people in northern Shaanxi?

People in northern Shaanxi have always been accustomed to "folk superstition of ghosts and gods, being confused by witches and ghosts, praying for blessings" (Jia County Records and Customs of the Republic of China). Besides, burial is popular in northern Shaanxi, so Yin and Yang, as a profession, have a broad living space in northern Shaanxi. It was only during the Cultural Revolution that Yin and Yang and activities related to Yin and Yang almost disappeared, but since the 1980s, activities of Yin and Yang have become very common. Yin and Yang, as people who communicate with the dead and the underworld, are also called "Shi Ping". However, when people in northern Shaanxi address Mr. Yin Yang, they avoid calling him "Yin Yang" directly. In general, they will add a word "teacher" before their surnames, calling them "Li" and "Li".
