In Guizhou, is it better to use telecommunications for broadband, or Tietong and Netcom?

It depends on where your home is. Netcom in the north has advantages. The south is still dominated by telecommunications. When you play games, you will experience more. If you choose telecom broadband to play games in the south, it will be very painful, because most servers in the south are telecom. As for Tietong, it is generally mobile at present.

I hope this helps.
