There is little violent crime against tourists in China, partly because the penalties are severe for those who are caught—China's yearly death-sentence tolls run into the thousands. Single women can move about Beijing without too much hassle. Handbag snatching and pickpocketing do occur in markets and on crowded buses or trains—keep an eye open and your money safe and you should have no problems. Use the lockbox in your hotel room to store any valuables. You should always carry either your passport or a photocopy of the information page and the visa page of your passport with you for identification purposes.
Beijing is full of people looking to make a quick buck. The most common scam involves people persuading you to go with them for a tea ceremony, which is often so pleasant that you don't smell a rat until several hundred dollars appear on your credit-card bill. "Art students" who pressure you into buying work is another common scam. The same rules that apply to hostess bars worldwide are also true in Beijing. Avoiding such scams is as easy as refusing all unsolicited services—be it from taxi or pedicab drivers, tour guides, or potential "friends."
Beijing traffic is as manic as it looks, and survival of the fittest (or the biggest) is the main rule. Crossing streets can be an extreme sport. Drivers rarely give pedestrians the right-of-way and don't even look for pedestrians when making a right turn on a red light. Cyclists have less power but are just as aggressive.
Beijing's severely polluted air can bring on, or aggravate, respiratory problems. If you're a sufferer, take the cue from locals, who wear special pollution masks, or a scarf or bandanna as protection.
Distribute your cash, credit cards, IDs, and other valuables between a deep front pocket, an inside jacket or vest pocket, and a hidden money pouch. Don't reach for the money pouch once you're in public.
