Instrument in a Chinese temple (4)
I believe the answer is:
gong
'instrument in a chinese temple' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for gong that I've seen before include "Medal; forty down" , "Source of summons" , "Dinner chime or slangy medal" , "Resonant metal disc" , "cross, possibly" .)
