The entry time and departure time in Beijing are five years, and the company has paid a three-year social security prosecution period.

Do you mean that the company paid a three-year social security prosecution period when both the entry time and the departure time in Beijing were five years? If it is not paid in the first two years, it is overdue.

According to the social security network, the limitation period for employees to recover social security is generally 2 years, because the employer has not paid social security fees for its employees, and the statutory mandatory recovery period for employees is 2 years. If the employer violates the labor law and has not been discovered by the labor department within two years, and has not been reported or complained by employees, the labor department will no longer investigate and deal with it, and the social security fee collection department may order it to pay or supplement the social security fee within a time limit. So if you have worked in the company for five years and haven't paid it in the first two years, you will find out after leaving the company that the statutory mandatory payback period has passed.
