What is the minimum level of flexible employment in Huai 'an, Jiangsu?

The minimum level of flexible employees in Huai 'an City, Jiangsu Province is 60%.

If flexible employees pay 20 years of social security according to the lowest grade, there is another option, that is, they can pay 100% 15 years. Which of these two payment grades will enjoy a higher level of pension benefits? This may be a problem that puzzles a considerable number of flexible employment groups.

Because they really don't know how to choose the payment grade of social security, and as flexible employees, they can freely change different payment grades every year.
