Exploratory Studies of External Qi in China

This paper briefly reviews five different cate-gories of major studies on external Qi (EQ) that were performed in China: physical detectors, chemical dynam-ics methods, biological detectors, life-sensors detectors, and detectors using human body. Here, the focus is on the pros and cons of each detector. The extant literature suggests that some form of bio-information (about which we know very little) plays a critical role in the effect of EQ. From physical detector to human body detector, the energy sensitivity decreases, while the bio-information sensitivity increases. Future studies should use more bio-logical or life detectors to increase our understanding of the bio-information within Qigong.
