Safety
Generally Beijing is a very safe city and given little attention by criminals. Nevertheless, as with any large city, Beijing has its fair share of pickpockets. In crowded places, carry your bag in front of you and keep small change in your pocket to avoid opening your wallet.
You’ll encounter beggars around temples and in neighborhoods frequented by foreigners. They are often mothers or children, many of whom can be aggressive; they’re desperate, but not usually harmful.
While traveling in China, please pay attention to traffic for safety’s sake.
