I just returned from a trip to Beijing and Hong Kong and wore shots every day. There was no issue. On only 1 or 2 nights when going out did I wear jeans. For those that say everyone wears long pants, remember that the climate in Beijing isn't that hot in the summer (and the smog keeps you out of the direct sun). And Beijing can be fairly cold in the winter, so wearing long pants isn't really that big of a deal most of the year anyway.

However, Hong Kong is tropical and in the summer it is sweltering. Unless you have been there for at least a month and are accustomed to it, you would be crazy to wear long pants if you are going to be outside any length of time. Yeah, the locals all wear long pants, but it is because they are coming and going to work - not to tourist spots.

Besides, if you look at the photos of men with ..... out - most taken at tourist attractions, about half of them are wearing shots.
