Hi Oliver no your english freeview box won’t work over here unfortunately.
I have also tried to look into digital, as the standard Chinese TV has only 1 english channel, which is a world news channel. A friend of mine has got Satellite TV (which I believe has american stations), but she paid quite a lot of money for the installation, and had to sign for 2 years. I think the best way to get English TV is to get a good internet connection and a good VPN, then you can get on BBC iplayer, 4OD and ITV player.
