Do some research before going there

It's a well known fact that everything there must be fast, it's their culture, so they don't give a fuck if u triggered or not, u don't wanna kena marah, then do like a Hongkie, be rush and fast

Would rather visit China than HK, Shanghai was top notch for me, everyone was polite and like the other said they will be friendlier if they know u are from Mahresia, surely there were rude uncivilized arses but those are mostly their local tourists from lower tier cities.
