Abstract： According to the Chinese medicine theory “the stomach governs decomposition of food and drinks， and stomach meridian is full of qi and blood”，Prof. LI Feng clarified that the location of chronic atrophic gastritis is the stomach， and the pathogenesis is associated with the spleen and the liver. Professor LI proposed that the treatment should give priority to fortify the spleen， be based on warming the middle， and attach importance to soothing the liver. In addition to the principles above， he propounded a combination of three methods that functioned as medication guidance： Yiqi Xiaopi method，Wenzhong Sanjie method，and Shugan Hewei method. Besides，he thought that dietetic therapy，non-medicine therapy， and adjustment of mood can be adjuvant treatments of the three methods， so as to inhibit gastric atrophy and intestinal metaplasia both caused by chronic atrophic gastritis.
