Excuse me, how cold it is in winter in Hong Kong, and how thick clothes and pants do you wear?

Vaguely, the hotel on the first floor seems to be talking about it. Heating is not everywhere in winter in Hong Kong. In winter, it runs all over the street in a down jacket, wearing a thin layer inside, but definitely not short sleeves. Because Hong Kong is humid, it was not really cold before, so there will be a cold wave in recent years. This is because the weather has changed so much in recent years that people will freeze to death. I suggest you take a thick coat and cotton-padded jacket, and wear a single piece inside instead of trousers. As for covering the quilt, you should choose the appropriate thickness according to your physical condition, but of course it doesn't need to be too thick.
