Abstract: The history of ancient Shu dated back to the history of west Shu before B. C.316 when Qin defeated Shu. Written records of Ancient Shu originated from the late of Warring States Period and Qin and Han Dynasties, such as 'Shu started from Renhuang emperor', 'King of Shu was an offspring of Yellow emperor' 'Yu was from Guangrou, Wenshan county' 'the ancient emperors before Shu were Cancong, Bohu, Yufu, Kaiming'. Textual research on the times of related historical documents and historical events proves that the concept of ancient generation clan in modern times was based on legends, which were not historical facts but traditional culture. Recently, there is a tendency to 'believe in ancient legends' in Ba-Shu culture academe, which is harmful to discern the false legends from the genuine history, and prevents correct understanding to the truth of ancient Shu society.
