What happened was:
A group of China tourists was in Hong Kong’s subway. Everyone (even them) knows that eating is prohibited on the trains. Now these China people were eating noodles… NOODLES! (I mean I occasionally eat a bit of clean food like bread discretely, or drink from a bottle, but noodles is just too much.) A Hong Kong man steps in and tells them not to, and even calls the train conductor over. The China people deny that they are wrong and make a big deal, arguing like a boss even though they are obviously wrong. Even the child in the family of tourists speaks up and says to her mother “I think my mom made a mistake”, and her mother tells her to be quiet.
Next, on a tv show, a China scholar or whoever speaks about the incident. He says that every Chinese person should be speaking Mandarin, because Cantonese is a dialect. Even though the China tourists were in Hong Kong, where cantonese is spoken, everyone there should speak Mandarin to them because its the language of China. He then goes on to call the Hong Kong people “dogs”, with much conviction, because he thinks that Hong Kong is now returned to China, but somehow are reluctant to be under China’s rules.
Hong Kong people distinguish themselves from China people, because we have a different culture and we do not think like them. From a small age, my parents have dropped hints that they disliked people from the mainland, and I grew up under this philosophy. A long time ago, I thought my parents were prejudiced, but I have witnessed events and read the news, and since then I have learnt why. The mainlanders come to Hong Kong, and they are rude, they are obnoxious, and they behave as people do in China. They push and shove, shout vulgar things in public, spit on the ground, and have no shame in disregarding simple rules for their own benefit. But in Hong Kong, people are polite and are genuinely nice people. We don’t care what you do in your own country, but please don’t pull those things here in Hong Kong.
Foreigners rarely manage to distinguish between the local Hong Kong people and mainlanders, so when they see the Chinese in Hong Kong doing unspeakable things, they think that everyone in Hong Kong is like that. But Hong Kong has been independent from China for a while, and the public really despise the mainlanders, although there is nothing they can do about it because, technically, Hong Kong is part of China now. I acknowledge this fact, but I will never consider myself “from China”, no matter what people say. Hong Kong is not China.
