The theory of Feng Shui definitely exists, but not many people really understand it. That's why there are some doubts. I don't think it is a real existence.
As the saying goes, one destiny, two luck and three feng shui, this is what it means. Therefore, from this sentence, Feng Shui exists.
But there are two sentences at the end: four to accumulate yin virtue and five to study.
This means that it is more important to work hard.
So although Feng Shui has some influence, it cannot be said to be an absolute influence. Innate conditions still require acquired efforts to achieve success.
