Problem with immorality in China (3,7)
I believe the answer is:
tea service
'china' is the definition.
(I've seen this before)
'problem with immorality' is the wordplay.
'problem' becomes 'teaser' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'immorality' becomes 'vice' (vice can mean immoral behaviour).
'teaser'+'vice'='TEA-SERVICE'
'in' is the link.
(Other definitions for tea service that I've seen before include "crockery" , "that may be brought to the table" , "China pieces" , "China possibly" , "Cups, saucers, plates, etc" .)
