Pull out of Chinatown (3)
I believe the answer is:
tow
'pull' is the definition.
(tow is a kind of pull)
'out of chinatown' is the wordplay.
'out of' indicates the answer is hidden within the clue.
'TOW' is hidden within 'chinatown'.
(Other definitions for tow that I've seen before include "Pull along (a vehicle)" , "form of flax" , "Pull away" , "Tug" , "Haul" .)
