1. The Civil Servant Law explicitly prohibits civil servants from participating in business.

Chapter 9 Punishment Article 53 of the "Civil Servant Law of the People's Republic of China" Civil servants must abide by discipline and shall not engage in the following behaviors (14) Engage in or participate in for-profit activities, in enterprises or Hold concurrent positions in other for-profit organizations.

2. Handling of civil servants’ illegal participation in business activities.

Article 27 of the "Regulations on Punishment of Civil Servants of Administrative Agencies" that came into effect on June 1, 2007. Anyone who engages in or participates in for-profit activities and holds concurrent positions in enterprises or other for-profit organizations shall be given a demerit. Or a major demerit will be recorded; if the circumstances are serious, a demotion or dismissal will be given; if the circumstances are serious, a dismissal will be given.

Article 34: Punishment of civil servants in administrative agencies shall be decided by the appointment and removal authority or the supervisory authority (hereinafter collectively referred to as the disciplinary decision-making authority) in accordance with the administrative authority.

3. How to deal with the income obtained by civil servants who illegally participate in business?

Article 53 of the "Regulations on Punishment of Civil Servants of Administrative Agencies": Property and use of property obtained by civil servants of administrative agencies in violation of laws and disciplines Property that violates laws and disciplines shall be confiscated, recovered, or ordered to be refunded and compensated by other agencies in accordance with the law. If the property obtained in violation of laws and disciplines should be returned to the original owner or holder, it shall be returned to the original owner or holder; if it is state property and should not be returned or cannot be returned to the original owner or holder, it shall be turned over to the state treasury.

As for family members doing business, it should be possible. However, judging from actual experience, although there are no prohibitive regulations, I personally recommend not to engage in fields that are related to the business managed by civil servants. Otherwise, if problems arise, they will not be reported. Is it easy to say?
