Where is the hometown of longevity in China?

China has six longevity towns, namely Zhongxiang City, Hubei Province, Bama City, Guangxi Province, Leshan City, Sichuan Province, Rugao City, Jiangsu Province, Karamay City, Xinjiang and xinglong village City, Liaoyang City, Liaoning Province. The longevity of the general elderly depends on the living environment, physical and mental health and eating habits, and very few reasons are related to heredity. Although the regional water and soil have a greater impact on the longevity of the elderly, the more important impact is the mood. As the saying goes, smiling for less than ten years will help the elderly to enhance their immunity and reduce the harm of diseases, while negative emotions will make the elderly depressed, accelerate organ aging, which is not conducive to metabolism. Spend more time with the elderly, send them warmth and prolong their life.
