This reminds me of an article I read online once about how obsessive people can get about numbers in Asian cultures. For them, it isn't about numerology, but the way things sound.
For example, 8 (Ba) is extremely popular, but it sounds like "to become wealthy" (Fa). People will go out of their way to get an address, phone number, car license plate or ID card with as many 8s as possible. Sichuan Airlines just spent 2.3 million yuan ($280,000.00) for the phone number 88888888. The 2008 Olympics in Beijing not only started on August 8th, 2008 (8/8/08) their opening ceremonies started at 8:08:08 pm local time.
On the other hand, 4 is considered incredibly UNlucky because the number (Si) sounds almost identical to the word for Death. In Asian countries, many buildings don't have a 4th floor, similar to the "missing" 13th floor older Western buildings. With the number 14, they get it both ways. If you call it "fourteen" then it sounds like Shi Si, "ten deaths". If you call it "ten and four" it sounds like Yao Si, "I want to die".
