Abstract: Professor Li Ji was one of founders of archeology and the first anthropologist in China. He worked all his life for archeological study in China, wrote many papers and books and had many pupils. Though his contribution was mainly reflected in the excavation of the Shang sites in Anyang from 1929 to 1937 and the study of cultural remains from the Shang sites from that time through 1979, he reaped rich fruits in other parts of the archeological research in China, for example, he also did important works in the realm of the paleolithic archeological research. Professor Pei Wenzhong said that: "it is difficult to study stone artifacts discovered from Loc.1 at Zhoukoudian, I began to learn archeology and learn from Professor Li Ji at first" (Pei, 1934). The excavation process in Loc.1 at Zhoukoudian was reformed in 1932. The new excavation adopted a method including a combination of test ditch and test square. This method had been used in the excavation of early stage in Shang sites in Anyand under the supervision of Professor Li Ji. When Upper Cave was excavated in 1933 Professor Pei adopted other excavation method which was formulated and named as "three dimension space record process" by Professor Li Ji and was used at first time in 1926 in excavation of the Neolithic site at Xiyin village of Xia County, Shanxi Province. In addition, Li Ji had contributed interesting ideas to the study of Zhoukoudian culture. In the present paper Professor Li Ji's life story is briefly introduced for helping the readers to know the historic background on which he gained the great achievements in the field of archeology.
