Should I get a refund if my salary is higher?

Legal analysis: if the company wants to return the overpaid wages, the employer can bring a civil lawsuit to the people's court and demand the workers to return the unjust enrichment.

Legal basis: Article 122 of the Civil Law of People's Republic of China (PRC) stipulates that the person who has suffered losses has the right to demand the return of improper benefits because others have obtained improper benefits without legal basis.
