"Street" is a general term with the longest history, the highest frequency and the most vigorous vitality among the street names in Chengdu. "East Street, West Street, Zongfu Street, Xiaobei Street and Datiankan Street" are really streets that can be seen everywhere. According to Mr. Ren Naiqiang (1894- 1989), the word "street" is not an ancient saying in the Central Plains, but "comes from Qiang, Shi, Shu, Bo and other national languages, indicating that the cities where clan leaders live are easy to concentrate, and it was only after the Han Dynasty that the word" street "was used to refer to Beijing's urban streets. Therefore, "street" can't be found in the Central Plains classics before the Western Han Dynasty.
