Attribute: There are five difficulties in health preservation, fame and fortune are immortal, and this difficulty is also full of emotions. In addition to this dilemma, the three difficulties are endless, and these four difficulties are well thought out.
Solve these five difficulties and five will exist. Although it is difficult to chew Huaying and breathe the sun, it is necessary to die and not dry. In your chest, you will believe in the sun, but Xuande will not pray for happiness, let alone seek happiness and life, but will postpone the return of this health-preserving calendar (Ji Kang's health-preserving theory)
