Gold leaf walls in Chinese family home for kids (9)
I believe the answer is:
orphanage
'home for kids' is the definition.
(I've seen this before)
'gold leaf walls in chinese family' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'leaf' becomes 'page' (page is a kind of leaf).
'walls in' is an insertion indicator (I've seen this in other clues).
'chinese family' becomes 'han' (Chinese dynasty).
'page' enclosing 'han' is 'phanage'.
'or'+'phanage'='ORPHANAGE'
(Other definitions for orphanage that I've seen before include "Parentless children's institution" , "home for kids" , "special home" , "Home for parentless children" , "Children's home" .)
