After Confucius's interpretations, the six classics became highly influential classics. However, who transmitted Confucian classics during the time from Confucius to the establishment of the five classics doctorates by Emperor Wu of the Han Dynasty? In addition, how and where were they transmitted? Traditional texts neither comprehensively covered nor consciously sketched such questions. On the other hand, the recently unearthed documents more or less complement in this regard. This paper is meant to integrate the materials from both traditional texts and unearthed documents to address these questions more comprehensively.
