For Chinese the number 8 is considered lucky just like the number 7 is considered lucky in the West. In China you have to pay extra to have the number 8 in your phone number or license plate. In addition, home and business owners like to have the number 8 in their address.So, why is the number 8 considered lucky in the minds of Chinese people. The main reason has to do with the pronunciation of the word for the number 8 in China. It is pronounced "ba" and sounds like the word for prosperity which is pronounced "fa". Another reason why the number 8 could be considered lucky is because it is a perfect symmetrical shape. You can cut the number 8 in half vertically or horizontally, and both halves mirror themselves perfectly. Perfect symmetry lends itself to perfect balance. In Chinese Astrology, perfect balance is considered the ideal.
