Metaphysics, also known as neo-Taoism, is also called metaphysics. It is a study and explanation of Laozi, Zhuangzi and Zhouyi, which originated in Wei and Jin Dynasties. Metaphysics is a trend of thought advocating Lao Zi and Zhuang Zi in China from Wei Jin to the middle of Song Dynasty.

Metaphysics is "profound learning", which is based on "ancestors narrate Lao Zi and Zhuang Zi", and Lao Zi, Zhuangzi and Zhouyi are called "San Xuan". Taoist metaphysics is also the only knowledge besides Confucianism that has been designated as an official school.
