Negative aspect of balanced Chinese philosophy (3)
I believe the answer is:
yin
'negative aspect of balanced chinese philosophy' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for yin that I've seen before include "Counterpart of yang" , "Complement of yang" , "principle accepted in China" , "Principle of cold and dark" , "Comedian Billy Connolly is the big one" .)
