This is the Taoist way of keeping in good health, which is feasible. However, Taoist priests need to cooperate with a certain mentality to avoid the valley. Ordinary people want to avoid the valley and need to be guided by professionals. For example, if they want to take part in the valley camp and go to the scenic spot for a few days to eat (exercise regularly and drink nutrient solution), it can be regarded as clearing the intestines and detoxifying. If you don't know what to do, don't rush into the valley and don't turn into a hunger strike.
