In the Chinese place, Amy had the duck (4)

I believe the answer is:

amoy

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

'in the chinese' is the definition.
I can't tell whether this defines the answer.

'place amy had the duck' is the wordplay.
'place' is an anagram indicator (I've seen 'placed' mean this (placing the letters)).
'had' is a charade indicator (letters next to each other).
'the duck' becomes 'o' (resembles zero - 'duck' in cricket).
'amy'+'o'='amyo'
'amyo' is an anagram of 'AMOY'.

Can you help me to learn more?

I've seen this clue in the Evening Standard.
