"Generally, after a job seeker goes through the entry formalities, it marks that he or she becomes an employee of the company, and that day is the day when he or she starts to work. Of course, under certain circumstances, the company will notify him or her of the time of work. But in most cases, he or she will go to work immediately after going through the entry formalities.
 China's laws stipulate that written labor contracts should be concluded when establishing labor relations. The Company shall sign a written labor contract with the employee within one month of the employee's entry. If no written labor contract is signed, the employee shall be paid double wages from the second month. "
 Legal basis
 Article 10 of the Labor Contract Law of the People's Republic of China (2012 Revision) [Conclusion of a written labor contract] To establish a labor relationship, a written labor contract shall be concluded.
 If a labor relationship has been established but a written labor contract has not been concluded at the same time, a written labor contract shall be concluded within one month from the date of employment.
 If an employer and a worker conclude a labor contract before employment, the labor relationship shall be established from the date of employment.
