He said that human beings study the changes of seasons and everything in order to identify the interests of everything, so as to seek advantages and avoid disadvantages, which is beneficial to the health of life and achieve the goal of longevity. For example, five kinds of things, too sweet, too sour, too bitter, too spicy and too salty, will damage life.
