Of course, the so-called "East Sea" in this "East Sea of Happiness and Sadness" has naturally been debated by many people for many years. According to experts' research, "Happiness as the East China Sea, longevity as the South Mountain" means "Happiness as the East China Sea", which is now known as the East Pole of China. There is a strange stone on the hillside, which can be compared with the "the first strange stone in the world" of Putuo Mountain, a Buddhist country in Haitian, and is engraved with the first blessing in the world. Legend has it that people who arrive here can increase happiness and longevity. In fact, the so-called experts are just bloggers laughing. Since it is Donghai Mountain, how can there be "constant water"? Longevity of Nanshan: Some people say that Nanshan in Shaoyang, Hunan Province belongs to Nanshan in Longevity of Nanshan, while others say it is Zhong Nanshan in Xi 'an. Opinions vary, and they have been arguing endlessly, but they can't reach an agreement. For young pine, Nanshan young pine, located at the southernmost tip of China and 20 kilometers away from Sanya, Hainan, is second to none. Not Lao Song, the scientific name is "Dragon Blood Tree". It appeared in the Cretaceous dinosaur era and is a living fossil in plants. Listed as a protected tree by UNESCO, it is on the verge of extinction on a global scale. However, there are as many as 60 thousand plants growing in Nanshan area of Sanya City, with different ages. The oldest is said to be over 6400 years old. No wonder it is said that "longevity is better than Nanshan", which is really a great ambition! Of course, there is also a legend about her: a long time ago, one year in Qiongzhou, it suddenly became dark, with thunder and lightning, and it rained cats and dogs for seven days and seven nights. On the eighth day, there was a loud noise and the sky was falling. Qiongzhou broke away from Chinese mainland and became an island. Life on Qiongzhou Island is dead and wounded. All rivers have changed their paths, all mountains have changed their shapes, and some rivers and mountains have disappeared. Strangely, only Nanshan (now Aoshan in Sanya, also called Nanshan) is safe and sound, not a single tree or grass is damaged, and no one living on Nanshan is injured, let alone dead. Legend has it that Nanshan people who experienced this sudden collapse lived for hundreds of years and eventually became immortals.

In 748 AD, 35 people including Jian Zhen and his disciples set sail from Yangzhou. When crossing the sea for the fifth time, I was caught in a hurricane and drifted from Wan Li to Ningyuan Estuary (now Haishan Wonder Scenic Area) in Zhou Zhen (now Sanya). I had no strength at all. People in Nanshan found them and saved them. As soon as they came into contact with the land of Nanshan, they immediately opened their eyes and their spirits came. They lived in Zhou Zhen for more than a year, built Dayun Temple and spread Buddhist culture.

These strange things are passed down from mouth to mouth, so people call Nanshan fairy mountain. More and more people come to Nanshan to play and live. Legend has it that people who have been to Nanshan are sick and healthy, and they all live long. Because Nanshan was intact in the sudden subsidence. Because people who have been to Nanshan live a long life, people often wish others a long life with longevity. The phrase "longevity is better than Nanshan" has been used ever since.
