Need advice - what type of doll

My oldest daughter is going to China on a business trip tomorrow.  I would like her to bring me back a doll.
She will be there until July 2nd and will go to many cities.    I thought if she went to Shanghai she could visit the Barbie store, but then thought maybe she could find  a different type of doll not readily available in the U.S.. Any suggestions would be appreciated!  Thanks in advance.
