The development of space-time view promotes the theoretical construction of Chinese medicine

while the form and development of meridian sinew theory is destined to have close relationship with space-time. The spacetime signification of meridian sinew is analyzed from Chinese coinage law. The property of time（dynamic state

rhythm

etc.） and the extensity（multi-dimension

multi-element

etc.） of meridian sinew is explained. Taking this as the entry point

based on the space-time aspects of developing

relating and whole

the authors explore the framework of meridian sinew theory.
