Labor Contract Law of the People’s Republic of China, Article 19

If the term of a labor contract is more than three months but less than one year, the probation period may not exceed one month; if the term is more than one year but less than three years, the probation period may not exceed two months; and if the term is fixed for three or more years or is open-ended, the probation period may not exceed six months.

An employing unit and a worker may agree upon only one probation period.

No probation period may be stipulated in a labor contract that expires upon completion of a given job or in a labor contract for a term of less than three months.

The probation period shall be included in the term of a labor contract. If a labor contract only provides for a probation period, that period shall not stand and the term provided for shall be the term of the labor contract.
