You can resign after signing a two-year labor contract. China's law stipulates that the laborer can terminate the labor contract by notifying the employer in writing 30 days in advance. The laborer may terminate the labor contract by notifying the employing unit three days in advance during the probation period. According to the Reply of the General Office of the Ministry of Labor on Issues Related to the Termination of Labor Contract by Laborers, the notification of the laborer to the employer in writing 30 days in advance is both a procedure and a condition for the termination of labor contract. The laborer shall notify the employing unit in writing 30 days in advance to terminate the labor contract without obtaining the consent of the employing unit. After 30 days, the laborer shall apply to the employing unit for the cancellation of the labor contract, which shall be handled by the employing unit. This is the right that the law gives workers to choose their own occupation, and it is a basic right of workers, which is usually called "the right to resign". When a worker exercises the right to resign, he/she can unilaterally terminate the labor contract by giving a thirty day prior written notice. The labor contract can be officially terminated at the expiration of thirty days without the consent of the employer.
