Who are Mr. Geng who loves ancient books?

A pen named Xia Zilang's Cold Talk about Laozi is absolutely thorough, and it is comprehensive and suddenly enlightened to interpret ancient knowledge with the latest knowledge of modern scientific psychology. There is no boasting here. I am a doctor of history from Zhejiang University, and I have at least some discernment. I have seen dozens of versions of Tao Te Ching, and only the cool "Talking about Laozi" can be regarded as appealing to both refined and popular tastes. There is no mystery. The author can easily explain extremely complex philosophy with simple stories, and it is well-founded and all-encompassing. To tell the truth, I didn't believe there was such erudition in the world before. After reading it, I recommended it to my high school son, and he liked it very much. We are both big fans of him now.
