My classmates asked me to work for SF Logistics in Danyang City, Zhenjiang City, Jiangsu Province. Let's help to see if it's true.

I am from SF, not SF, but what kind of administrator are you talking about? We are only 3000, so let's just say that unless there is a courier in a good area, you should be careful, especially in pyramid schemes, comrades-in-arms and relatives can cheat, let alone classmates. If you really want to go, you must prepare for the worst. Think about what to do once it is really a pyramid scheme. Maybe it will be wrong then. Without long-term worries, there will be near worries. Bless your friends.
