China Development Bank is a policy bank, and its staffing belongs to public institutions, while the four major commercial banks belong to enterprises. China Development Bank is relatively stable, and it is less challenging than the four major commercial banks. Basically, it provides loans for large-scale projects, while commercial banks provide services for individuals and enterprises, which is challenging. The pros and cons depend on personal ideas. If I am inclined to be stable, I will choose to work in China Development Bank.
