Our team specially went to Jinzhai, the hometown of longevity, to investigate the reasons that may make the elderly live longer. After a few days' visit, we went to two towns in Jinzhai County, both towns and villages, and visited about 30 elderly people over 80 years old. Through communication with them, we began to understand their eating habits, physical condition and the great concern of the government for them. We have also summarized some good habits of the long-lived elderly, and the influence of these good habits on their lives is worth discussing. I hope each of us can live a long life.
