Chinese with painful condition is to spend time relaxing (4,3)
I believe the answer is:
hang out
'to spend time relaxing' is the definition.
(I've seen this before)
'chinese with painful condition' is the wordplay.
'chinese' becomes 'han' (Chinese dynasty).
'with' means one lot of letters go next to another.
'painful condition' becomes 'gout'.
'han'+'gout'='HANG-OUT'
'is' is the link.
(Other definitions for hang out that I've seen before include "Frequent place" , "Regular meeting place" , "Spend time relaxing" , "lodge" , "Haunt" .)
