Traditional culture believes that all things have animism, and the "Book of Mountains and Seas" records that ancient rare and rare animals possess magical abilities. The "Laozi Jade Policy" of the Han Dynasty stipulates that animals must practice for 300 years before they can transform into human form. "Baopuzi" mentions the lifespan and ability of animals that become sperm. There is also the saying that animals "ask for seal". If the fight for seal fails, they need to practice again.
• Special circumstances of animals becoming spirits: Guo Pu of the Eastern Jin Dynasty opened the back door for the fox to shorten the time it takes to transform. Ji Xiaolan of the Qing Dynasty mentioned in "Notes of Yuewei Thatched Cottage" that all things become spirits irregularly, and objects can also become spirits. It is easy for foxes to become spirits, but it is difficult for objects to become spirits.
• The theory that animals are not allowed to become spirits after the founding of the People's Republic of China: Legend has it that after the founding of the People's Republic of China, the Imperial Star Ziwei and the Human Emperor made a hundred-year blood contract, which blocked all kinds of gods, demons, ghosts, and animals, so that they could not come to the human world or become spirits. It also cited the thunderstorm night in Lujiazui in 2012 and the Humen Bridge shaking without wind in 2020 as examples of supernatural events, teasing the possibility of catastrophes related to cultivating immortals in the future.
