What's the difference between the first and second social security files?

The first social security file is 60% and the second social security file is 80%. The higher the level, the more you get, and the second social security file gets more insurance money than the first social security file. The social insurance of the insured is divided into four grades: the lowest grade (40%), the first grade (60%), the second grade (80%) and the third grade (100%).
