Media and even the Chinese president have been critical of how some Chinese travellers have behaved on trips. On a September trip to the Maldives, Chinese President Xi Jinping suggested Chinese citizens be “a bit more civilised when travelling abroad.”I wasn't very impressed with the Chinese tourists I encountered in Europe a few weeks ago, that's for sure. They were very loud, even in churches! At one church in Helsinki there was a young woman who kept shushing people as they entered the church, but as soon as they got inside they acted like a mob--you'd be surprised how loud people can be when they're trying to take group pictures. And let's not forget the cutting in line, the pushing and shoving, etc. It may be cultural for them, I don't know, but they were *not* in China and should conduct themselves more in accordance with local custom.
With more than 100 million Chinese travelling in 2014, misbehaviours have grabbed headlines worldwide. Among the most extreme: defacing an Egyptian sculpture, throwing boiling water on a flight attendant and urinating outside.
Our guide through the Hermitage was particularly hostile to Chinese tour groups, and with good reason, from what I saw.
