Colonial, Local or Imperial?

The Chinese in Singapore are an interesting lot. Unlike our cousins back in the motherland of a few billlion who can be considered somewhat more culturally homogenous, we here have evolved, in my opinion, along 3 subclasses. On the left of the picture is the 'Colonial Chinese', with the 'Local Chinese' in the middle and the 'Imperial Chinese' on the right. As their names suggest, each subclass has its unique characteristics, behaviours and practices. Correct me if I am wrong but I don't seem to see many Colonial ones around any more. Where have they gone to? Hmmm...
