Who has the best Feng Shui course at present?

Most teachers in this industry can't do it. They have many titles and are strategists on paper. Some are packaged like masters, grandstanding, and some are very high-level, but they don't want to spread the news. I've seen a lot. Later, by chance, I met Liang Weibin, a teacher who has both ability and political integrity and treats others sincerely. He also wrote many books about the Book of Changes and Feng Shui. Searching for dragons and acupoints, mysterious secrets and so on.
