Perhaps you should try some spelling variations:
china aus » china als, china aids, china a
china auf » china a, china air, china adb
yang july » yang judy, yang jun
long han » long chain, long thanh, long haul
han than » phan thanh, han chang, harm than
yang jui » yang judy, yang di, yang xi
yang yi » yang di, yang xi
wang » wing, wan, lang

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: long han than ((china aus) OR (china auf)) ((((yang jui) OR (yang yi))) OR (yang july)) wang hua ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long han than ((china aus) OR (china auf)) ((((yang jui) or (yang yi))) or (yang july)) wang hua ;~".
• Adding a wildcard symbol may retrieve word variants: long han than ((china aus) OR (china auf)) ((((yang jui) or (yang yi))) or (yang july)) wang hua ;*.
