The head office of China Construction Bank is divided into more than 30 provincial branches according to domestic provinces and cities. Below provincial branches, some provinces will divide secondary branches according to prefecture-level cities, and district-level branches of municipalities directly under the Central Government such as Shanghai and Beijing are equivalent to secondary branches of other provinces. Below tier-two branches, grass-roots branches (in some places, called sub-branches) will be divided according to business outlets. This constitutes the internal management framework system of CCB.
