Qi is a kind of substance with the energy of life message. Qi is the leader of
blood and the power of cell metabolism. Qi is a kind of comprehensive and complex substance
which only exists when the person is alive. Qi is with life message, undulatory and
corpuscular. In terms of physics, Qi includes the energy of motion, such as electromagnetic
energy, universal gravitation energy and mechanical energy. In terms of biochemistry, Qi
includes the energy of cell, cell communication，chromosome, mRNA, tRNA, protein and unknown
life message energy. The biomacromolecules in human body with life message all exist in the
environment of normal temperature, and according to the physical theory, the
biomacromolecule which is the carrier of life message will emerge the infrared ray ether
wave when being stimulated. The transmission speed of Qi in the body is the same as the
speed of heat effect emerged by infrared rays in human body fluid. Qi is a kind of energy
and can be detected by energy detecting apparatus. Only living things have Qi and can’t be
alive without blood. That is to say, blood is the origin of Qi.
