Beware of nice strangers who speaks good English specially near famous spots like tiannamen square and forbidden city in beijing its a big mafia and they have 1001 ways to scam u, I was scammed by a group of univ students who said they hang around there to practice their english with tourists, I was bored and went to have tea with them, they have 3 types of menu with different prices and ended up paying around 350 egp for a couple of cups of tea in 2007
