Doctor needs transfer to a city of China (7)
I believe the answer is:
dresden
'city of china' is the definition.
'dresden' can be an answer for 'china' (a type of porcelain). I'm not sure about the 'city of' bit.
'doctor needs transfer' is the wordplay.
'doctor' becomes 'Dr' (abbreviation).
'transfer' indicates an anagram (I've seen 'transferring' mean this).
'needs' with letters rearranged gives 'esden'.
'dr'+'esden'='DRESDEN'
'to a' acts as a link.
Can you help me to learn more?
(Other definitions for dresden that I've seen before include "German city known for its china" , "Type of china" , "source of 26 [CHINA]" , "Dr needs to be in the German city" , "'German city, almost totally destroyed by British air raids in 1945 (7)'" .)
