I really enjoyed this book especially the history chapter with the insides of the ancient scripts that was preserved by the Li family. Also the in-depth discussion about the philosophy of tai chi is really interesting. 

Summary:

"Tai Chi: The True History & Principles" by Lars Bo Christensen offers an in-depth exploration of Tai Chi, delving into its historical roots, philosophical foundations, and core principles. Christensen, a seasoned Tai Chi practitioner and scholar of Chinese culture, presents a comprehensive examination of the art form.

The book sheds light on ancient texts preserved by the Li family of Tang Village for over three centuries, notably discussing "The Thirteen Movements," a sequence of postures documented in the late 16th century. These movements, originating from the Thousand Year Temple, incorporate the eight trigrams and five phases, elements still integral to contemporary Tai Chi practice. Christensen also delves into the dualistic philosophy of Yin and Yang, central to Daoist and Confucian thought, emphasizing the importance of balance and interdependence in life.
