Lucky numbers have always played an important role in Chinese culture.They are considerations that need to be taken into account by the Chinese under lots of circumstances.When selecting apartment floors,phone numbers or license plate numbers,Chinese people tend to choose the lucky numbers.Chinese people think the even numbers are more propitious than the odd numbers.For example,"2" represents "harmony",while "6" represents "smooth going".And the number "8" is the favorite number for the Chinese because the sound of "8" (ba) is identical to "fa" in Cantonese,which means prosperity,wealth and status.The opening ceremony of Beijing Olympics started at 8 o'clock on August 8th, 2008,which could not have been a coincidence.
