There are many scams that newcomers here must learn to avoid. The classic scam involves English speakers inviting Westerners to come to a traditional Chinese tea ceremony. After a cup or two, there’s a bill for a huge amount, with some hefty bouncers there to enforce payment. Ouch.
Online shopping in China or with Chinese companies can be a big risk. Here is a list of Chinese retail websites that are reported to be fraudulent. One friend of mine bought a computer on one of these sites and lost his money. One of the warning signs that he should have known about: they told him they don’t accept credit cards but needed the money sent via Western Union. That’s the same as handing someone cash. No recourse. No protection. Don’t ever buy anything via Western Union payments! Ever.
If you are coming here for a job, there a plenty of crooks that will sign up foreigners for jobs here that turn out to be closer to slave labor. They promise to get a visa faster than should be possible, and some smuggle people into the country illegally or bribe an official at a “diplomatic desk” to get the victim into the country. They then keep the person’s passport, making the person completely vulnerable and at risk of imprisonment or deportation if they don’t cooperate, etc. It’s human trafficking. Don’t fall for these scams. They are aimed largely at people from less developed countries.
Remember, there are people looking for ways to exploit you. Be suspicious. Be nervous. Don’t give your passport to people you don’t trust. Don’t pay people in advance with cash. Don’t let a charming smile lure you into an out-of-the-way place where you’ll have to pay a lot for your tee, or pay even more to replace your teeth. China is a great place abounding in kind, honest people, but the few crooks here and everywhere else force us to stay on our guard at all times. Be careful.
