The city center of Chengdu is not Tianfu Square, but the intersection of Qionghuan Lane and Wenwu Road. There is a bronze plate (latitude 30°40′ north, east longitude 104°04′), which is the origin of Chengdu. Geographically speaking, it represents the precise location of the core area of the city and uses this as a starting point to calculate the geographical distance between the city and other cities.
