China's administrative organs, institutions, companies and enterprises have many directors and deputy directors at different levels. For example, a higher-ranking director may be equivalent to a ministerial level, and a lower-ranking director may not even be a departmental level. Therefore, according to the specific units and roles, the level and responsibilities of the director and deputy director may be different.
However, regardless of the level, the director and deputy director usually have specific administrative responsibilities and powers. They may be responsible for specific projects or tasks, and may be responsible for making decisions, managing or performing specific tasks.
As for professional titles, the director and deputy director are not professional titles themselves, but administrative leadership positions. In some cases, they may be given additional titles or ranks to reflect their importance in a particular role. For example, they can be defined as deputy senior engineers and associate researchers. But this is not applicable in all cases, and the specific title or level may vary according to the different units and roles.
Generally speaking, the vice presidents of grass-roots courts are all administrative leaders, and they may have specific titles or grades, but this may also be different due to different units and roles.
