In the 60s

the author first started from the theory of Brecht and the "repetitive study" of his works

writing some papers

academic essays and commentaries

and then the author was not content with things as they were

having the intention of looking for breakthrough in the "relationship of Brecht and Chinese problem" research. However

it was hindered by the disdain of academic circles and author's ignorance of Chinese culture. In mid 80s

with a female German sinologist's enlightenment and drive

the author started from the blueprint problem of The Good People of Sezuan

determined to study the Chinese ancient philosophical knowledge well

and continued to follow the direction of "the relationship between Brecht and Chinese cultural tradition"

writing The Good People of Sezuan and the Chinese Cultural Tradition which had the value and caused a sensation. Since then

the author had gradually put his energy into the study of the relationship between Brecht and Chinese philosophy

and gradually discovered Brecht 's great absorption and integration of Chinese culture. In face of many Brecht 's quotations which are similar to the Analects of Confucius Prose author also began to come up with a idea to study it with method of studying ancient literature as translation and annotation.
