Born in today’s Zhejiang (浙江) region, Liu Ji (刘基), commonly known as Liu Bo Wen (刘伯温), was a highly accomplished astronomer and diviner. He became a national scholar after passing the central government final examination at the tender age of 19, and he was praised for being just and impartial by the people he served. Liu Bo Wen later rejected promotions and left his position as a government official to study and research in his hometown. Despite subsequent political troubles, he returned to his hometown to focus on his studies. At the age of 48, he accepted an invitation to assist the Ming Dynasty’s Hong Wu Emperor Zhu Yuan Zhang (朱元璋) in conquering the Song Dynasty and starting the new Ming era.
Liu Bo Wen wrote “Essence of Heaven” 《滴天髓》, which famously captured nearly the full completion of Traditional Chinese Metaphysics. This book is one of the five legendary works in the study of Traditional Chinese Metaphysics within the Eight Characters of Zi Ping system, contributing significantly to the development and near-completion of this system during the Ming Dynasty period.
