In Journey to the West, what does success in 2899 mean?

It is the theory of practicing health preservation: February and August refer to February, and February is full of energy from cold winter to warm spring-but it is easy to be restless and lose! In August after the midsummer, the essence is easy to sweat-Ruiqi powder must be replenished! Therefore, in February and August, it is necessary to nourish and supplement; By 1999, Chongyang is in autumn, and the autumn is crisp, the grain is abundant, and the rice is new, and the spirit is strong. I am ready for the winter, and I will repeat it every year! ! !
