Immortality originates from Taoist philosophy in China's traditional culture. It involves people's cultivation and practice, aiming at prolonging life and restoring physical health and vitality through various methods and techniques. The concept of longevity and rehabilitation can be traced back to ancient Taoist thoughts, especially in the Taoist classic Zhuangzi. Taoism believes that people should pursue longevity and health, and achieve this goal through inner cultivation and physical and mental harmony. In Taoist thought, the concept of emphasizing natural harmony, maintaining inner peace and fostering survival and longevity has become the basis of longevity and rehabilitation.
