Based upon the definition and characteristics of science

the fallacy that traditional Chinese medicine（ TCM） is pseudo-science is refuted. The architecture of human civilization is depicted as a butterfly and the position of TCM is illustrated

which tells that TCM is an art with a core of system science. The differences of TCM and western medicine are compared by use of Taiji diagram

while their space scales in research are schematically presented on the basis of QIAN Xuesen’s division. Hence it is pointed out that TCM and western medicine need to go in opposite directions

i. e. TCM Top-down and western medicine Bottom-up

detailed examples are given. Nexus（ meridian）and diaforamen（ acupoint） are the part in TCM which have the most scientific characteristics. By adoption of exegesis and classics

it is argued that "nexus is interstitial gap

diaforamen is cavity"from imago

science and philosophy.Combination of Chinese Hexateuch with English word-building to translate TCM terms can construct TCM discourse system with Chinese characteristics

which is beneficial to the understanding in scientific connotation of TCM

as well as the integration of TCM with western medicine. The rebirth of TCM from the ashes will significantly prompt the great rejuvenation of Chinese nation and human peace.
