Contract workers of the Market Supervision Bureau can be corporate shareholders, because contract workers are not on staff and there are no restrictions.

Strictly speaking, the Market Supervision Administration should be called the Market Supervision Administration. Its regulatory responsibilities cover the original industrial and commercial administration, quality and technical supervision, intellectual property (trademarks, patents, copyrights), prices, and catering supervision. (Other areas are the functions of the Food and Drug Administration or the Health Bureau), alcohol product supervision and other departmental responsibilities.
