There is no job information in the personnel file. Can I use the social security payment certificate?

I can't. The social security payment certificate can't prove the working materials of the personnel file, but it can prove the length of service, but many things in the personnel file can't be proved, such as age, type of work and special type of work. These things still need to be found in personnel files, which generally record the name, age, gender, date of entering the factory, type of work, how long the special type of work has been done, and so on.
