Follow most of Chinese revolutionary's code of principles (5)
I believe the answer is:
dogma
'principles' is the definition.
(I've seen this before)
'follow most of chinese revolutionary's code' is the wordplay.
'follow' becomes 'dog' (I've seen this before).
'most of chinese revolutionary's code' becomes 'ma' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'dog'+'ma'='DOGMA'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for dogma that I've seen before include "fixed opinion" , "Set of principles laid down as incontrovertibly true" , "Go mad (anag.)" , "Body of creed" , "Belief, precept" .)
