China city for which doctor needs transfer (7)
I believe the answer is:
dresden
'china city' is the definition.
(city famous for its porcelain china)
'doctor needs transfer' is the wordplay.
'doctor' becomes 'dr' (synonyms).
'transfer' indicates an anagram (I've seen 'transferring' mean this).
'needs' is an anagram of 'esden'.
'dr'+'esden'='DRESDEN'
'for which' is the link.
(Other definitions for dresden that I've seen before include "SE German city" , "Send Red out to the German city" , "Red Ned's in the German city" , "Germany city - reddens (anag)" , "Dr needs to be in the German city" .)
