Yes, but here is the main point. The airport in Guangzhou looks quite good except that you may have to take only one out of the 4-5 exits built for the other doors aren't in service (bottleneck culture) which means you may have to walk too much and for the taxis wait and overpay much as well; Changde (Hunan) has just got a well finished new terminal too and it does have new seats , however, there're the rules of cabbies in front and that with the authorities supporting them.

As for the UK, although Heathrow may not look as nice as the newly built Chinese airport, you will likely be allowed to get out of any of its public exits and get a cabbie worth the price. Is it your experience that the licenced London airport taxi drivers negotiate in front of the terminal doors under the supervision of the security guards there? And, do they so blatantly ask for a double fare?
