Is it true that Feng Shui self-study course 100%?

In short, it is basically true. But there is one thing that no expert can deny, or avoid not answering, that is, secrets or know-how are easy to keep secret! So many mysterious things are formed in this way. What ordinary people can't master, only a few people can master it to become masters. Furthermore, learning Zhouyi and Feng Shui requires a good understanding, and the ability of understanding and epiphany must be strong, otherwise it will be boring to learn for a lifetime. Just like Chinese medicine, many Chinese medicine practitioners regret learning Chinese medicine. They deny their poor understanding but deny Chinese medicine!
