In his early career, Sun Yinshi was hired by Shi Hao to teach his sons such as Shi Miyuan and Shi MiJian in the Donghu Academy. For this reason, Sun Yinshi not only built close relations with the Shi families, but also had opportunities to communicate with some famous scholars. Thus, during this period, Sun established a solid base for his further developments in political and academic fields. After Shi Miyuan controlled the Song court for more than twenty years, however, he suffered a lot of critiques from contemporaries and scholars in later periods, especially for his decisions on enthroning Emperor Lizong, killing Prince Ji and negotiating with the Jurchen and Mongol regimes. One example is the comments written by the Qin scholars in the front of Sun Yinshi’s book Chuhou Ji. Mainly based on the information provide by Chuhou Ji, this article researches the relationships between Sun Yinshi and Shi Miyuan. Sun Yinshi once worked under Qi Chong, the Governor of Sichuan, so he was familiar with military situations of Sichuan. After the death of General Wu Ting, Sun suggested the Song court to eliminate the power of the Wu families in Sichuan armies. However, Han Tuozhou, who controlled the Song government, refused to accept Sun’s project, and appointed Wu Ting’s son Wu Xi to command Sichuan troops. This decision then resulted Wu Xi’s rebellion in 1206. After Han Tuozhou died, the Song court finally confirmed the value of Sun’s suggestions, so gave Sun posthumous honor and rewarded his offspring. For this reason, the biography of Sun Yinshi was recorded in the local gazetteer Quaiji Xuzhi and his book Chuhou Ji was able to be printed. Thus, both the career of Sun Yinshi and his posthumous reputation were closely related to Shi Hao and his son Shi Miyuan.
