It gets confused with Mao’s Chinese philosophy (6)
I believe the answer is:
taoism
'chinese philosophy' is the definition.
(Taoism is a Chinese philosophy)
'it gets confused with mao's' is the wordplay.
'gets confused with' indicates an anagram (I've seen 'get confused' mean this (I've seen this in other clues)).
'it' anagrammed with 'maos' makes 'TAOISM'.
(Other definitions for taoism that I've seen before include "Religious movement" , "Maoist (anag) -- Chinese religion" , "Confused Maoist in Chinese religious system" , "Chinese philosophical system" , "philosophy in China" .)
