Do you have a lucky number Many people have a special number and they hope that it will bring them good luck. In China, people think some numbers are lucky or unlucky because those numbers sound similar to some Chinese words with good or bad meanings.
For example, the word for number 8 sounds like "making lots of money" in Chinese. So, people think it is a very lucky number. Some people even spend much more money to have 8s in their phone numbers. Do you remember the Summer Olympic Games in Beijing It opened at 8:00 p.m. on August 8, 2008
The number 9 is also a lucky number because of its connection to the emperors of China. There were nine dragons on the emperors' robes(龙袍) and it's told in many ancient Chinese stories that the dragon has nine children. The number 9 also means "long lasting". In China, a man would send 99 or 999 roses to his lover with the wishes that the love between them will be long-lasting.
What's more, the Chinese think that the number 2 is lucky as it's said that "all good things come in pairs". For example, during wedding celebrations, you usually find pairs of red candles, double pillows and many other things in pairs. And people often give gifts in pairs for someone's birthday, wedding or other celebrations.

Because of this, many buildings skip the fourth floor. In Hong Kong, some buildings even skip all floors numbered with 4, such as 4, 14, 24 and 34.As a result, a building with 50 floors may have only 36 floors actually.
