Who has heard of teacher Xu Shixiong's Feng Shui and Environmental Design course? How's it going? Is the site effect good?

I didn't listen carefully, but after watching this video lecture by xu teacher some time ago, my thinking was clear. People like me who don't know anything about Feng Shui can listen to it roughly. It is estimated that the atmosphere will be better if the scene is present. I am very interested in this kind of lecture. Who has the information about this teacher's class? Remember to share it.
