I agree with this. Despite being in modern times, there are really a lot of places that decided to maintain and pass on their culture and tradition. There are many people as well who do this despite the technological advancement. There's nothing reallly wrong with it as long as they are not stooping on other people's rights and at the same time causing harm to those around them just because of their beliefs
Others didn't know that many professional and rich business people are applying feng-shui in their daily lives.
Even their respective own establishments always have a touch of feng-shui to bring luck. Look at them now, most are successful in their business. Of course, they don't just rely on luck but they also applied hard work, smark work, time and effort, perseverance, focus, and seriousness that's why they reached their decent status.
That also applies to professional gamblers. These people know that those feng-shui or lucky charms didn't affect their winnings but if they will combined luck beliefs + smart gambling, seems that is effective in the long run so they keep using that way.
Many great people were superstitious.
For example, the French Emperor Napoleon Bonaparte believed in omens. He sincerely believed in rock (fatum).
This is due to the fact that no matter how smart a person is, he is not able to fully understand the world around him. The human brain has its limits in the knowledge of the surrounding reality. After all, the human brain is just an evolved primate brain.
Therefore, a person fills in the gaps in his knowledge with faith or superstition. This does not prevent a person from being efficient and successful.
Therefore, feng shui is very popular (including in the field of gambling).
