If the company only provides dormitories for some employees, can it go to the labor bureau?

It is not a legal obligation for the company to provide dormitory for its employees. If there is no agreement in the labor contract, there is no agreed obligation. Then you can't sue the company at the Labor Service Bureau in this situation.

The Labor Bureau is a government agency in China, including the Labor Branch and the Labor Employment Service Center. The main duties of the Labor Branch are to implement the national, provincial and municipal guidelines, policies, laws and regulations on labor work, and organize the implementation of the labor development plan and annual plan formulated by this Municipality. The main task of the labor employment service center is to be responsible for the development and utilization of labor resources, urban and rural labor employment, floating employment and other specific services.
