If this belief gave good results then we would have seen completely different statistics from other countries on gambling in China where a very large number of people are committed to Feng Shui. But unfortunately there are also a lot of people who have become addicted to gambling and also a lot of people who are in debt because of gambling.
So faith has no effect on good luck.
Actually it is, "Faith has no effect on the MATH side of things". If we think about a player who believes in and uses Fengshui to "make him more lucky", and EVERYDAY he plays a casino game that has more than 3% edge against him, who does everyone believe will come out the winner after one year? The winner will be the casino, and the seller of Fengshui cat dolls.
