Like many others I have had some bad experiences with Chinese tour groups whilst travelling.

For example, I'll be standing in front of a painting when I'm suddenly bundled out of the way by a large group who force their way in. What makes me especially angry is that many are not even looking at the painting - they are all chatting away together or are playing on their phones.

And the spitting in public is a total turn-off.

But having said that, I found that the Chinese people I met in China itself were very polite and helpful.

Tour groups bond together in weird ways and it is that bonding which sees them supporting bad behaviour from members of the group.
