How do I complain about buying Shenzhen minimum social security when I go to work in Guangzhou?

If you find yourself working in Guangzhou, but the company only pays the lowest social security in Shenzhen, you can choose to complain. First of all, you can communicate with the employer to understand why they choose to do this. If you feel that you can't reach an acceptable result, you can complain to the local labor inspection department. Before submitting a complaint, you'd better prepare all relevant evidence, including salary certificates and other documents, to support your complaint. However, please note that this process may take some time and energy, so it is best to weigh the risks and benefits carefully before complaining.
