The rebirth of the phoenix was an ancient myth. According to legend, phoenixes were divine birds with extraordinary abilities and divinity. It was reborn from the fire and gained a higher life form and greater power. The story of the phoenix's rebirth could be traced back to the ancient Chinese Classic of Mountains and Seas. According to legend, phoenixes lived in the south and took the forms of birds, beasts, and humans. In myths, the process of the phoenix's rebirth was very mysterious. It needed to be reborn in the fire and obtain a higher life form and stronger power after rebirth. The reason why it was sometimes called Phoenix's Nirvana was probably because the word Nirvana itself had a mysterious and supernatural meaning. In Chinese, nirvana was a word with a profound meaning. It represented a state of transcending pain and suffering, a process of rebirth and ascension. Therefore, sometimes people would use the term " phoenix nirvana " to describe the outstanding performance of a person or thing, indicating that it had the ability and potential to surpass ordinary people. There was no clear answer to the question of which word was the correct one,"Hong" or "Phoenix". In Chinese, the words " Hong " and " Phoenix " were both common mythical creatures. Their appearances and characteristics were different. Some people think that "Chonghong" is the correct word because it is closer to the image and characteristics of "Phoenix" and has more mythical colors. Some people believed that "phoenix" was the correct word because it represented the mysterious and supernatural meaning of the phoenix. Whether it was the "Hong" or the "Phoenix", they all had certain cultural implications and symbolic significance.
