In Rushan, it has been passed down from generation to generation that Dashan is a treasured place that prevents miasma and prolongs life.

The average life span of people in this area has been very long throughout the ages.

The proportion of centenarians in the total population of Rushan City has exceeded the "Longevity Hometown" standard of 75 parts per million for many consecutive years, while the ratio of Rushan Coastal Tourist Resort is 5-6 times this standard; the average life expectancy ratio

The city is four percentage points higher. The total number of households in the three administrative villages is only 607, and there are more than 100 elderly people over 80 years old.

Dashan is undoubtedly the longevity district among the hometowns of longevity. In Xishan Village, since the establishment of the Central *** village-level party branch, the eleven party branch secretaries are still alive; in 2008, the village’s 96-year-old twin sisters Zhao Xiuxiang and

Zhao Xiuju received the "Big World Guinness Best" certificate from the Guinness headquarters in Shanghai on July 28, and was confirmed to be the oldest twin in China.

Is it a coincidence that China's oldest and many long-lived elderly people appear at the foot of Daru Mountain? Is it a coincidence between legend and reality, or is there an inevitable connection between the two?

With this question in mind, the author launched an investigation.

In Chinese mythology, Nuwa's purpose in creating humans from clay was to prosper the world and make the humans she created healthy, long and happy.

It is said that the Yellow Emperor, the ancestor of the Chinese nation, took his physical body and became an immortal and ascended to heaven.

The Bible also says that God, Jehovah, created Adam in the image of God out of clay, with the intention of allowing humans to manage the world.

God was afraid that Adam would be lonely, so he used one of Adam's side bones to make Eve to be Adam's spouse.

Satan, the animate and invisible devil, possessed the body of a snake and opened his mouth to tempt Eve and Adam to eat the forbidden fruit.

After being expelled from the Garden of Eden, Adam worked hard to support his family, but he still lived for 930 years before dying.

The origin of life is disease-free, and the secret of life is happiness.

People once imagined that there was some mysterious power in order to coexist with the world.

Qin Shihuang sent Xu Fu to lead the boys and girls across the sea to seek immortality and the elixir of immortality; Chang'e took the elixir and flew to the moon; Liu Chen and Ruan Zhao went to the rooftop and ate the elixir peaches, realizing that they had only been on the mountain for half a year, but they returned

What the family met later were their great-great-grandchildren seven generations later.

According to the spirit of the "Book of Changes", if the heaven is healthy, a gentleman will constantly strive for self-improvement; if the terrain is flat, a gentleman will be virtuous; the three talents of heaven, earth and man should become more and more harmonious and unified.

According to the principle that the five elements are mutually reinforcing and interfering with each other, there is always one thing in the world that is suppressed by another, so there should be no disease that cannot be cured.

According to the perspective of evolutionary theory, the process of evolution progresses in a good, balanced, and beautiful direction.

According to the information conveyed by genetic science, the age at maturity multiplied by eight is the life span rule. People should live to at least 150-200 years old.

A large number of examples show that human beings have been looking for methods and substances for health and longevity since ancient times.

So, do sisters Zhao Xiuxiang, Zhao Xiuju and the people at the foot of Dashan Mountain know how to live long and have longevity substances?

Song Lifu, who is committed to research on aging issues in Rushan, said in the "Survey on the Causes of Longevity of Centenarians in Rushan City": "Longevity genes, stable social environment, good family environment, appropriate lifestyle, positive life attitude, etc. are not what Rushan is talking about.

It is unique and also exists in other areas, but the excellent natural environment is the biggest advantage of Rushan and is unmatched by most areas." According to his research conclusion, why is the natural environment unmatched elsewhere?

The climate is unique.

There is no scorching heat in summer and no severe cold in winter. This sentence is most appropriate to describe the climate of Dashan.

Darushan Scenic Area faces the sea and is surrounded by mountains. In summer, the sea breeze brings coolness and is naturally cool.

In winter, the north wind is in season, and the mountains are like walls, blocking the cold and storing warmth.

What is unique is that this kind of "wall" is "multi-layered". The entire Rushan area is formed by Kunyu Mountain, Mashi Mountain and other mountains to form a crescent-shaped barrier, blocking the biting north wind, forming a warm winter style "Rushan".

"Climate"; Darushan and the surrounding mountains form another barrier, once again blocking the wind from the north. Coupled with the temperature regulation effect of the sea, a unique "Darushan climate" is formed.

Its moderate temperature, appropriate humidity, and fresh air are extremely pleasant.

The soil quality is unique.

The site of Darushan Scenic Spot has hilly landforms and sandy land.

According to tests conducted by the agricultural department, its soil is "nutritional soil" and "non-toxic mud", rich in many minerals needed by the human body and does not contain any harmful elements.

The grains, fruits and vegetables produced here have pure taste.

Sandy hilly land has good water permeability and drainage, so even if chemical fertilizers and pesticides are used, they cannot remain in the soil.

The water quality is unique.

There are many wells around Darushan, and the water is milky white. People call it "white pulp water" because the water is sweet.

The white milk water appears at the foot of the Big Milk Mountain in the myth of maternal love. People feel it is magical and regard it as the mother's milk. Therefore, such well water is also called the "Holy Milk Spring".

In the Dashan area, even if the well water is not milky white, the drinking taste is quite good.

After testing and identification by the health and other departments, all the well water is weakly alkaline and is a rare high-quality drinking water.

The property is unique.

The Dashan area is rich in seafood and mountain plant resources.

The large open water area stretching from Rushankou in the west to Langnuankou in the east has smooth tides and small wind and waves. The Rushan River and Huanglei River rush into the sea, bringing in a large amount of natural bait, which is very suitable for the growth of shellfish.

Therefore, the quality of oysters, sea red (mussels), clams (variegated clams), etc. produced along the coast of Dashan has been famous throughout the country from ancient times to the present.

Oysters, in particular, have a beautiful legend.

It is said that when the Three Holy Mothers transformed into Big Breast Mountain, for the sake of the future livelihood of their children, some of their milk dripped onto the coast and turned into shellfish clinging to the rocks.
