The number 6 is also considered lucky in China. The word for 6 sounds like a word "Liu" that means `flowing freely' or`everything will go smoothly'. Because of this, the number 666 is considered one of the luckiest numbers in Chinese culture. It is often displayed in shop windows and neon signs. License plate AW6666 was recently sold for $272,000 yuan (US$34,000) in an auction to an anonymous bidder in Guanzhou.
