What are Wang Huying's six books?

If you want to learn the prophecy of the Six Classics, the ancient book Add and subtract Oracle Inscriptions is the first one. Modern books, Liao Moxiang's best in the 20th century. In the 2nd/10th century, Wang Bingzhong, a native of Shenyang, wrote The Repatriation Debt-A Forecast Guide for Six hexagrams, which is the most systematic and accurate, and can be used as a teaching material. It is also the most profound. It can be seen that the teacher's theory is accurate and solid, and he has rich practical experience. There are many examples of various hexagrams in the book. I have been wandering for more than ten years. I have read this book in detail and highly recommend it.
