Outbreak surges, engulfing Chinese city (4)

I believe the answer is:

aksu

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

'chinese city' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'outbreak surges engulfing' is the wordplay.
'engulfing' indicates a hidden word (I've seen 'engulfs' mean this).
'AKSU' is hidden within 'outbreak surges'.

Can you help me to learn more?

I've seen this clue in The Hindu.
