Lucky numbers are obviously bullshit. The house addresses, the hotel floors, etc, are all based on numbers and aren’t worth discussing here.
It’s annoying that the Chinese give numbers so much focus, and it even seems that feng shui didn’t used to to focus on them at all. (For trivia’s sake, the reason ‘4’ is unlucky is simply because in Mandarin it sounds almost the same as the word for ‘death’. Ditto for 14. The Chinese seem to think this is profound, but this has got to be an example of the dumbest numerology possible. Especially since in Mandarin every word, without exaggeration, sounds identical to about a dozen others.)
