From the perspective of diet, I think the relationship between man and nature is that the diet of human body should adapt to its natural environment. For example, people living in a humid environment eat more spicy food in moderation, which is conducive to dispelling cold and dampness; Spicy food is not suitable for people living in a dry environment, so the eating habits of various regions are often related to their geographical environment. Diet in different periods throughout the year should also adapt to the climatic conditions at that time. For example, people often like to eat red mutton, fat beef hot pot, instant-boiled mutton and so on. In winter, this can enhance the body's ability to keep out the cold; In summer, people often drink dark plum soup and mung bean soup. It has the effect of relieving summer heat. These are the embodiment of the correspondence between man and nature in diet and health preservation. From this perspective, the correspondence between man and nature is to adapt to the weather, and the more basic meaning is to protect one's body. Only when you have a body can you have life, and only when you have life can you have mental activities and physiological functions, and you can better "adjust your mind", and then "form and spirit are in harmony", and finally "form and spirit are in harmony, and people will live their lives."
