Cultural tips
The Chinese are fond of even numbers, which are considered as fortunate. The number "8" or "ba1" has a similar pronunciation to the word "发财", meaning getting rich. People believe that the number "8" could bring them good luck. When choosing telephone numbers or some other comparatively fixed numbers, they would like to pick up those with 8. Similarly, the number "6" or "liu4" is often associated with the meaning of "smoothness". Many people like to choose a date including the number "6" for their wedding. In contrast "4" or "si4" is the least favorable number just as "13" is considered as the least favored number in western countries. This is because the number "4" sounds like the word "死", meaning "death" in Chinese.
