he went on to teach at chinese universities including jinan university, yenching university, and tsinghua university in beijing. from 1934 to 1938 (and again from 1946 to 1949) he was chair of the department of philosophy at tsinghua. it was while at tsinghua that feng published what was to be his best-known and most influential work, his "history of chinese philosophy" (1934, in two volumes). in it he presented and examined the history of chinese philosophy from a viewpoint which was very much influenced by the western philosophical fashions prevalent at the time, which resulted in what peter j. king of oxford describes as a distinctly positivist tinge to most of the philosophers he described. nevertheless, the book became the standard work in its field, and had a huge effect in reigniting an interest in chinese thought.
