Good use of social security payment app in fact there are a lot of, easy social security ah, 51 social security ah, what, the service is good, the online operation is very convenient, but these companies are not the same service fee charged, I myself with the easy social security, is because of the charge is cheap, a month is only 40 dollars, other companies are more than a hundred it, and then cheaper, the company is not very reliable, or else it is a small company, it may not be the best. Maybe one day it's gone, easy social security is the best overall view.
