I'm more into superstitious since only believers see the difference while non-believers can't explain how things work, especially inside gambling where most of the time it's about luck and how you'll going to play with your emotions nad controls. Fengshui is available around
selected places where Chinese culture was being adopted.
Not an expert and also not that kind of believer, I will not argue if there's other people who see this as effective as it can be.
That's okay if you prefer superstition because people will choose what he likes. But we agree that this is a culture from China that has developed rapidly and even in some countries, Fengshui is still used because they still trust it to get information. Maybe ordinary people who do not know about things like this will never know what and how and it is up to them to respond.
It's pseudoscience but its method isn't scientifically based. I guess you're believing that it's science-based because of the calculation. But if you'll analyze the whole thing and also research what it means, you'll find that it's just all about superstitions. As being applied to lives and how to get luck, then it's also applicable to gambling and you'll see gamblers believing on it will say that they've been lucky because they've followed a certain suggestion from feng shui like putting some vase on the north side of the house, etc.
It's not scientific but it includes things that are complicated to explain, especially for people who don't understand superstition, Fengshui, and others. Maybe it's superstition but there are still people who will believe it and use it. I only know that Fengshui is about the position of how we should arrange the layout or position that can give positive energy to be in harmony and can also give positive energy to our lives.
