What animal are you talking about flying into the sky and turning yellow?

Goshawk. Yellow, yellow dog. Flying the yellow flag means releasing goshawks and hounds to hunt.

The source is Jin's "Bao Pu Zi Jin Dan": "Its camp is either glorious or profitable, or it flies far away from the Central Plains, or leaves a cup to cook with the soup."

Bao Puzi is a Taoist classic compiled by Hongyi in Jin Dynasty. There are 8 mouths inside and outside Bao Puzi, 20 of which have been treated by immortals, and 50 of them are famous for their political gains and losses, staff reduction and blog promotion.

Ge Hongdan's Lin Baozi in the Eastern Jin Dynasty is divided into internal and external chapters. Today, there are 20 internal articles, on immortals, refining books and forbidding things, and 50 external articles, on political gains and losses, personnel or not. There is no literary theory criticism in Shi Jun, Shang Bo, Ci Fu and Wen Xing.

This book summarizes the immortal theory since Wei and Jin Dynasties, establishes the Taoist immortal theory system, and inherits Wei Baiyang's alchemy theory, which is a great achievement of alchemy in Wei and Jin Dynasties.

Internal and external:

Bao Puzi's inner chapter mainly talks about immortal prescriptions, changes in ghosts and gods, health preservation and longevity, and belongs to Taoism (referring to immortals). Its contents can be summarized as follows: discussing Shen Yu's ontology to prove the existence of immortals, discussing the manufacturing method and application of drugs, discussing the study and application of various prescriptions, discussing various bibliographies of Taoist scriptures, and explaining the universality of world practice.

The outer chapter of Bao Puzi mainly talks about all kinds of things at local meetings, which belongs to the background of family, and also shows that the author thinks that Haixian is the first thing to be frozen. Its contents can be summarized as follows: on the gains and losses of the world, electric customs, the law of governing the people, judging whether the world is home or not, advocating the preservation of treasures and waiting for time, self-cultivation and thinking: on playing the virtuous, loving the people, taking care of garbage alone, being refined, cultivating self-cultivation and so on.

In a word, Bao Puzi integrated metaphysics with latitude theology, square wood with Dan, Dan with Fu, Confucianism with God and earth, thus establishing his theoretical system of divine sin.
