It is difficult to define the jurisdiction of different departments, including personnel department, discipline inspection department, credit department, personal business department, company department, organization department, mortgage department and car loan department. The hierarchy of banks is very strict. The director is not necessarily a big official, after all, there are presidents and the like.

Even office directors are generally difficult to act across departments. Banks have professional titles, and directors do not necessarily have high professional titles. Banks usually have multiple departments, which can be divided into several lines according to their business: retail, company, interbank funds, credit, finance, operation, administration, science and technology, legal compliance and so on.
