Thank you for visiting this TCM and acupuncture information website.
If you have previously been to this website, you might have
noticed that some of the pages on ancient historical ideas and
holistic thinkings related to Chinese metaphysics are temporarily taken offline.
This is because I will be revamping the whole website and be moving
those information into a new \"Ancient Chinese Culture\" section
so as to reflect a more current perspective on the interpretation
of some of the fundamental concepts as well as to include
some of the latest information in the area.
But if you have just found this website for the very first time, I welcome you again and
wish you could find what you require and, hopefully, you could also be benefitted
from reading the articles I published on this website.
