When it comes to the law of life, it means that the arrangement of the day should form a good law. For example, life should be regular, go to bed early and get up early according to everyone's habits, or go to bed late and get up early, so it is best not to go to bed late. Three meals a day should be timed, such as breakfast at 6: 30, lunch 12 and dinner at 6: 30. According to the four seasons of the year, the time of daily life and diet can be adjusted appropriately, which is what Chinese medicine calls "conforming to the four seasons".

Some people have more opportunities to eat out, which can easily lead to unreasonable diet. Such as overeating, irregular diet, uncontrolled diet, picky eaters, etc., will lead to long-term overnutrition or unbalanced nutrition, leading to diseases caused by unreasonable diet such as hyperlipidemia, hypertension, diabetes and obesity. Chinese medicine says that "sorghum is thick and full of boils", which means that eating more fat and sweet can make people grow boils. Excessive drinking can cause fatty liver and alcoholic cirrhosis. Therefore, if you want a reasonable diet, the best way is to eat it at home, because you can eat it in moderation according to your physical condition.

This can prevent cardiovascular and cerebrovascular diseases or delay the occurrence of some middle-aged and elderly diseases. Eat five flavors skillfully and keep healthy scientifically-people's tastes vary widely, sour, sweet, bitter, spicy and salty.
