This book is really good! It covers many aspects of ancient Chinese astronomy and calendar, giving me a deeper understanding of the wisdom of the ancients. Thinking about my friends and family, they will also be interested in this content. Just like what is said in the book "Observing phenomena and playing with divination", we can also understand the laws of nature by observing celestial phenomena. This is not only a book with rich knowledge, but also a treasure trove of food for thought.
