The health care methods from pre-Qin to Han Dynasty pay attention to both internal and external cultivation, and the specific methods mainly include promoting qi, diet and guidance. All these methods have a common feature, that is, "form" and "spirit" are equally important. From the characteristics of health culture, people's subjective initiative is expressed in another way, emphasizing that individuals must actively enhance their ability to adapt to the social environment through "nurturing" in order to achieve the goal of health and longevity. As for how to "cultivate its nature", Huangdi Neijing proposes to strive to be "indifferent and empty", and the specific requirements are "to eat its beauty, follow its course, enjoy its customs, and not admire it". While admitting the objective reality of natural laws, Taoism also believes that "heaven" means "inaction". Starting from this topic, Taoism inevitably requires "human nature" to do nothing like "heaven" and "be content with what it can" This refers to people's spiritual and temperament cultivation.
