These solar terms indicate a change in climate and tell us that we should take good care of our health and adjust our bodies through diet so that we can better adapt to the new solar terms. From the beginning of this period, this journal specially invited Prof. Liu Shaogui to explain different aspects of keeping in good health with the purpose of keeping fit, adjusting diet, practice body and so on. Hope to help readers self-care health. --editor
