yang jie » yang jin, yang xi, yang yi
yang jui » yang judy, yang xi, yang yi

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yan wang) or (han chang)) tuan hua rene ((((yang jie) OR (yang jui))) or (yang di)) hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan wang) OR (han chang)) tuan hua rene ((((yang jie) OR (yang jui))) OR (yang di)) hong yu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (han chang)) tuan hua rene ((((yang jie) OR (yang jui))) or (yang di)) hong yu ;*".
