What should I do if I didn’t pay social security when I worked at Fenggang Security Works Company?

You can pay it yourself

Security practitioners in China must abide by the laws of the People's Republic of China and other local regulations. Starting from me, I must strictly control myself, have a decent style, lead by example, be fair in dealing with things, have a high sense of responsibility for my work, and never neglect my duties. Strictly implement the instructions of superior leaders, resolutely complete tasks and implement them in place. Strictly abide by relevant disciplines. Any violation will be punished according to the "Regulations on the Administration of Penalties for Security Violations". Special problems and emergencies will be reported immediately, and we will fully cooperate with superior agencies and units to deal with them in a timely manner, and fully coordinate the work of relevant departments in the area of ??responsibility. Provide relevant materials truthfully and accurately to eliminate problematic incidents in their bud.
