It is said that “those who don’t know history is bound to repeat the mistakes of times past”. The Chinese DO know history and are always talking about their 5000 years of recorded history.
They.remember the humiliations of the 19th and early 20th Centuries as if it was yesterday. NEVER TO BE REPEATED.
Like Americans don’t like anybody interfering in their internal affairs (or electitions) the Chinese don’t like outsiders meddling in theirs. They are as nationalistic and patriotic as anybody.
Hong Kong was/is a reminder of the humiliation of earlier days and the last such reminder to be eradicated.
Likewise, most Chinese look at Hongkeys as rich spoiled brats that did not suffer the hunger of the “Great Leap Forward”, or the chaos of the “Cultural Revolution”.
The Hongkeys in turn look down on the mainlanders as uncultured and pushy people with no manners.
It is going to take some time to get them to accept each others as equals and fellow Chinese. Besides, the Hongkeys doesn’t even speak proper Mandarin, but insist on using Cantonese dialect as their “official language” (English is widely used in business and administration)
