agree, some years ago, I travelled Australia, there were many mainland Chinese travellers; many foreigners misunderstood my c6 & me & other HK tour participants to be mainland Chinese; I heard a lot of bad comments from some local Aussie; Aussie might think Chinese didn't understand what they said or criticised us in front of us purposely (might know we knew what they said)
I didn't say anything but one time in a big theatre - an Aussie forgot to take a coat which laid on a chair, I picked up & handed to that Aussie, he was glad to thank me...I knew it was only a trifle but I hoped he could change his thoughts that some Chinese had good characters
my c6 said that some foreigners in Shanghai really saw some big 6 made shit on the streets
the foreigners were very shocked to see that & felt very scary but local big 6 saw & felt nothing & passed by
