SF Express's envelope. I'll pack the things and seal the envelope when I get it back. Will direct delivery be required to open the express envelope for inspection?

I will. Now SF will open every express package. Powder. Liquid. Cigarettes in RMB. . . You can't send any. Afraid of smuggling. Now you will be asked to write down the market value. It's how much you express. But if you want to send RMB, I'll teach you a way. Take a worthless thing (wrapped). Like headphones. There is a cardboard in the package. Hide the money behind the cardboard. )。 Then put the money in that package. Then you deliver that thing. SF opened it and saw headphones. You won't see the money. So he can deliver it for you. However, there are certain risks. You'd better be mentally prepared.
