chang mae » chang ha, changes made
zhang zhi » zhong zhi, wang zhi, zhang wei
dean tan » tan tan
ying jin » jing ji, yang jie

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: zhang yang yang ((dean tan) OR (dean a)) ((ying jin) OR (yang jin)) ((chang mae) OR (zhang zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yang yang ((dean tan) OR (dean a)) ((ying jin) or (yang jin)) ((chang mae) or (zhang zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yang yang ((dean tan) OR (dean a)) ((ying jin) or (yang jin)) ((chang mae) or (zhang zhi)) ;*.
