1. The Shanghai headquarters was established on the basis of Shanghai Branch, and now it is also a set of people and two brands. In addition to the responsibilities of the original Shanghai headquarters, it is also responsible for the central bank's open market operation, financial market monitoring, financial information analysis and research, financial product research and development and trading, regional financial cooperation, etc., and also performs the duties of Shanghai Branch. That is to say, it is an upgraded version of Shanghai Branch, because it has fulfilled some responsibilities of the head office, so it is called headquarters.

2. The Beijing Business Management Department is actually the business management department of the head office, or it can be called Beijing Branch.

3. Normally, the level of Beijing Branch and Shanghai Branch is the same, and they are both directors. However, Shanghai Branch has been upgraded to the headquarters, so some leaders are well-matched. For example, a vice president of the head office is also the director of Shanghai Headquarters, and the deputy director is a director at the bureau level, but other personnel levels are the same as those of Beijing Management Department.
