Heads of trade and industry caught hiding illegal practice from China (3,3)
I believe the answer is:
tai chi
'practice from china' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'heads of trade and industry caught hiding illegal' is the wordplay.
'heads of' says to take the initial letters.
The first letters of 'trade and industry caught hiding illegal' is 'TAI CHI'.
Can you help me to learn more?
(Other definitions for tai chi that I've seen before include "Chinese martial art and system of callisthenics" , "form of self-defence" , "system of exercises" , "'Chinese form of slow physical exercise (3,3)'" , "Chinese exercises" .)
