Three Thousand Taoist Teachings Were Taught in a Dream, Did They All Come True?

Gu Fan dreams about going to the same world every night. Eight years, three thousand nights. In his dream, he had been a Taoist master and an emperor of heaven. He transformed into a Confucian sage to open up Confucianism and Taoism, and also transformed into the Netherworld to create reincarnation. There are also those notorious Lords of Taboo, with whom Gu Fan once drank and had fun. It's a pity that everything is just a dream and cannot be taken seriously!
