Is Mr. Guangyan accurate?

Teacher Guang Yan is not a liar. Teacher Guang Yan is not a liar because if you believe in Feng Shui, you have it. If you don’t believe it, you don’t have it. In several cases, the feng shui issues mentioned by Teacher Guang Yan have indeed worked. This also shows that Teacher Guang Yan is not a liar and is still useful. The word Feng Shui first appeared in the "Burial Sutra" written by Master Guo Pu in the Jin Dynasty. It was used to explain the selection criteria for Yin Zhai, which is the resting place of the deceased. Later, it was gradually improved and applied to Yang Zhai.
