With the accelerated pace of life, modern people generally feel stressed, unwell and have sub-health symptoms. In fact, there are two main reasons for illness: First, the water, air, soil, vegetables and fruits in the environment are polluted to varying degrees by highly industrialized society. These toxins are not excreted in time after entering the human body through various channels, and remain in the body for a long time, thus becoming "diseases"; Second, life pressure, excessive tension and some bad living habits, such as staying up late, drinking too much alcohol and tobacco, liking to eat junk food such as fried food and smoking, directly lead to "yin deficiency". So modern people have to make up for it.
