The Book of Changes is difficult to learn. I want to recommend a reliable place. I've always wanted to learn the Book of Changes, and I admire it.

I recommend Wuxing Pavilion, which was founded by Sun, a famous contemporary geomantic scholar of Yijing and president of China Institute of Traditional Culture. Although Mr. Sun is nearly sixty years old, he still insists on teaching in person, so that every student can learn the real culture of China, pass on the Book of Changes from generation to generation, and help more people answer questions.
