Which is the best to learn, four pillars and six pillars or Feng Shui?

I introduced Bazhai, followed by Kong Xuan. Now I am studying in Trinity, and I am completely self-taught. I'm afraid we should start with four pillars and six pillars. It's too difficult to understand. I participated in blind numerology halfway. However, I feel that after learning three or three, the basic knowledge should be almost the same. You can consider learning four pillars, adding up to two or three years. Let's just say new discoveries are made every day. Things are not simple, and it is difficult to apply them to practice. Be sure to go on a field trip, such as the Ming Tombs and the tombs of great men. It's just getting started.
