This is the third article that reports my observations at the Sinology Institute of Leiden University by the Wife Singel in Netherlands. The contents also reflect my study notes in the courses and a good memory that could serve as an academic reference for other scholars. The article consists of four sections: (1) Survey of history and personage of the Sinology Institute, describing the development of Leiden University and the successive deans of the Institute. (2) Survey of cultural and historical relics as well as ancient books and records collected in the Sinology Institute, reporting the relics exhibited in the Institute and the book reservation in the library. (3) The rubbings from two steles of ancient China: “The stale of commemorating the prevalence of Nestorian Christianity in China” and “The stale of recording the imperial edict of the Yuan Dynasty to grant The Cross Temple”. Both steles described the Roman missionaries preaching Christianity in ancient China. (4) One poem written by Li Hong-zhang during his visiting Netherlands in the 19th century, and one stele-“The stele of recording the Chong-Sheng Monastery in Da-Du of the Yuan Dynasty” that described the Buddhism in the state of Liao in the 10th century.
