Haunt Chinese ethnic group with painful disease (7)

I believe the answer is:

hangout

I'm a little stuck... Click here to teach me more about this clue!

'haunt' is the definition.
(I know that haunt can be written as hangout)

'chinese ethnic group with painful disease' is the wordplay.
'chinese ethnic group' becomes 'han' (I can't justify this - if you can you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'painful disease' becomes 'gout'.
'han'+'gout'='HANGOUT'

Can you help me to learn more?

I've seen this clue in The Telegraph.
