There are four seasons in a year, and the characteristics of the four seasons are different. People should grasp the characteristics of the four seasons and appropriately increase or decrease their clothes. For example, when winter comes, don't always stay in a warm room, go outdoors to adapt your body to the cold in winter to resist the arrival of the cold current in winter. If you catch a cold, that's another matter. Keeping warm is still the most important thing. Just like knowing how to solve a cow, you can easily walk along the seam of a cow.

It is also helpful to cherish the reward of nature and go out to bask in the sun.

Then there is the problem of food. Remember to eat more foods with more vitamins, take the necessary fat and protein, and try to eat less or not to eat those supplements.
