This year may mark the 10th anniversary of Hong Kong's return to the motherland, but the cultural divide is still a wide one.
One Hong Konger told me when she went to a five-star hotel for a posh culinary event in Beijing, she was surprised to see many of the mainland guests, who had paid 2,000RMB (US$266.30) each were wearing T-shirts and jeans, when she wore a cocktail dress.
Then when they got tired of standing around eating hors d'oerves and drinking wine, they crouched down in the middle of the ballroom. She wanted to tell them if they were tired, they could sit in the chair.
When dinner was served, prepared by Michelin-star chefs, wine was served at the table. And my friend and her fellow diners swished the red wine in their glasses to let it breathe.
A woman at the next table wanted to emulate them, but when she tried to swirling the wine in her glass, it sprayed out all over the table.
I hope no one was wearing white.
Many Hong Kongers try to distance themselves as much as they can from their northern cousins. Some may think this is an arrogant attitude, while others say the differences are so great, the chances of fully integrating culturally is next to impossible.
However, money talks and no one in the Special Administrative Region can deny that China calls the shots when it comes to the Hong Kong economy.
Hopefully someone will teach them how to swirl wine in a glass properly and wear proper attire to high-class events soon. It's in everyone's best interests.
