Which of the three mountains and five mountains is Nanshan and which is Wanshou Mountain?

There is a Nanshan Mountain in the southwest of Sanya City, Hainan Province, which is backed by the vast territory of the motherland and faces the blue waters of the South China Sea. Master Jian Zhen lived in the mountains and preached for more than a year before crossing the sea to Japan. Since then, Nanshan has been regarded as a blessed place by Buddhists. There are still many long-lived elderly people in Nanshan area. Some people think that this is the factual basis of "immortality is better than Nanshan".

There is Nanshan in the south of Xi, also known as Zhongnanshan and Zhou Nan, which is one of the main peaks in Qinling Mountains. Mount Zhongnan is majestic, with dense forests and beautiful scenery. According to legend, Lv Dongbin and others practiced here, which is a famous Taoist mountain and tourist resort in China, and was famous in the Spring and Autumn Period.

Geographically speaking, Nanshan in Sanya is far from the South Pole. Life expectancy is longer than Nanshan. If it is understood that the life span of the elderly is as long as that of Nanshan, this Nanshan is very suitable. But Nanshan in Sanya was called Aoshan in ancient times, not Nanshan. As for the longevity of the elderly in Nanshan now, I am afraid it cannot be used as evidence. Because longevity is better than Nanshan, the original intention is not to "live as long as Nanshan old people." The Book of Songs is a collection of poems about 500 years from the early years of the Western Zhou Dynasty to the middle of the Spring and Autumn Period. Poetry 305 is mainly produced in Shaanxi, Shanxi, Henan, Hubei, Shandong and other places, and is the birthplace of Chinese culture. Xi 'an, the ancient capital, has a strong cultural atmosphere. Zhong Nanshan occupies a geographical advantage, and literary creation takes local materials, which will naturally be written in Zhong Nanshan. Life expectancy is longer than Nanshan. If it is understood that it is as strong as Nanshan and maintains the vitality of life as the dense forest of Nanshan, it is more appropriate to regard Zhong Nanshan as Nanshan in the Book of Songs. Judging from the long name of Zhongnanshan, it should be this.
