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, there are essential differences between them.

The origin of the word "nirvana"
If Mr. Guo Moruo hadn't created this story, the word "Nirvana" would not be as well known as it is now. The word "nirvana" is a Buddhist term, meaning death, silence, happiness, inaction, liberation, freedom and so on.
"Nirvana" is the highest realm of Buddhist practice, which also refers to becoming a Buddha. This means that after practice, you will eventually reach the state of carefree and detached from life and death. Only when you reach nirvana can you get rid of the six divisions in the wheel of karma. People generally call the death of monks and nuns in Buddhism "death", and now "nirvana" has become synonymous with the death of monks and nuns and other Buddhists.
