The theory of phoenix nirvana comes from Mr. Guo Moruo's book of the same name, which is not an ancient legend in China. In the ancient myths and legends of China, there is no saying that the phoenix will be reborn from the ashes. The phoenix in Guo Moruo's poem "Phoenix Nirvana" actually refers to the fairy bird phoenix in western legend. Although Guo Moruo translated the fairy bird Phoenix into Phoenix, they are completely different in essence.
In Guo Moruo's "Phoenix Nirvana", he said: "Phoenix burns itself to ashes every 500 years, and then rises from the ashes, circulating endlessly and becoming eternal life. Extended meaning: Phoenix is the messenger of world happiness. Every 500 years, it will bear all the unhappiness and hatred accumulated in the world, throw itself into flames, set itself on fire, and exchange the end and beauty of life for peace and happiness in the world. It is also after the body has experienced great pain and tempering that they can be reborn with a better body. "
