~ Only, Feng Shui or not, don't bet more than you can afford to lose. Just in case. 
We can always be strategic when it comes to gambling and we could also rely on our personal beliefs but we can't expect others to have the same strategy or belief as we do. Fengshui I think won't work especially for those who don't believe in it. It's just a good thing that we have the freedom to rely on our beliefs, culture, and faith in gambling. Absolutely. In a free world we can do whatever we want for our entertainment as long as it doesn't hurt others. But the thing is that when you, relying on your beliefs, put all your family's money at risk, there's a good probability of someone being hurt. Someone close to you, someone you love. Don't do that.
In addition to this matter, All gamblers who enter a gambling do not want to lose, but most of them want to win big and get the real luck and not the bad luck of playing as a gambler. So this is one of the reasons that other gamblers believe that they hold the Feng-shui of the Chinese people because they have nothing to lose if they hold this kind of superstition and apply it to their gambling habit.
