How can an unidentified person remit money back to China in the United States?

If you really can't, let him hide it in a book or a gift. I heard that postal parcels are also opened in domestic post offices, which I think is quite damaging.

Then, it must be sent to China by US Postal International Express or registered mail, and remember to write down the domestic phone number of the payee, so that things can be contacted at the post office.

Also, don't send too much money at a time. If it falls, the loss can be minimized. I just used it once for a friend last week, but I was a little nervous and afraid of dropping it when I tried it for the first time. But express delivery is guaranteed, which is faster and safer than surface mail. The cost depends on where you send it in China, usually more than $25. If this is a big city, I don't think it will be lost. Second-and third-tier cities are hard to say.

If you have no identity, this method is not a long-term solution. As far as I know, Wells Fargo's Wells Fargo has the business of remittance to China, which is cheaper than Western Union.
