Bottom line: Shoubi Nanshan is not young.

This is a traditional couplet, wishing the elderly a long life.

This pair of couplets has a good meaning and is widely used among the people. Its duality is stable and uniform, and it belongs to working pair.

There is a legend about "Happiness is like the East China Sea":

? A long time ago, in Luhuitou Village, Zhuyaya County, a young man named Afu saved an old woman. It turns out that she is the third daughter of the East China Sea Dragon King. Now there is a great drought in the world, and she is here to tell the kind people that they only need to drink three mouthfuls of seawater in the East China Sea, and when they come back, they will dig up the ground to produce water, cultivate crops and make a fortune. In a word, you can get what you want.

Ah Fu drank three mouthfuls of seawater as she said, and all his wishes came true. After that, the villagers in Luhuitou Village will go to Dadonghai to drink three mouthfuls of seawater whenever they want to do something, and all their wishes come true.

The kind villagers in Luhuitou Village told this secret to everyone who came to visit the East China Sea. Therefore, people who have been to Dadonghai can have all the best as long as they drink three mouthfuls of water from Dadonghai.

People in Luhuitou Village say that this happiness is given by the East China Sea, so they often say that they are as happy as the East China Sea.

The auspicious phrase "happiness as the East China Sea" has been passed down to this day.

"Longevity is better than Nanshan" also has a legend:

? 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 City), and I had no strength at all. People in Nanshan found them and saved them. As soon as they touched the land of Nanshan, their spirits came. They lived in Zhou Zhen for more than a year, built Dayun Temple and spread Buddhist culture.

The story spread, so people called Nanshan fairy mountain. More and more people come to Nanshan to play and live. Legend has it that people who have been to Nanshan live a long life if they get sick or not, so people often use "longevity over Nanshan" to wish others a long life. The phrase "longevity is better than Nanshan" has been used ever since.
