Nine Trigrams and Six Elements Three-Dimensional Feng Shui is an innovative feng shui system that combines traditional Chinese metaphysical wisdom with modern environmental science. It was founded by Qian Zhenkai (courtesy name Rongdu), director of the Qiancheng Yishu Academy. With the Nine Trigrams of the I Ching as its core theoretical framework and the laws of Six Elements energy as a complement, this system moves beyond the limitations of traditional flat feng shui to build a three-dimensional spatial model. It aims to achieve harmony between humanity and nature through precise analysis of the interaction between environmental energy fields and human fortune.
