tang min » sang minh, yang mind, tang li
hong ghi » zhong zhi, hong g, hong hai
yang ya » yang yao, yang yi, yang ka
yang xi » yang di, yang yi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang ya) or (yang xi))ng ya hua gene ((tang min) OR (chang min)) ((jeong ghi) or (hong ghi)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang ya) OR (yang xi))ng ya hua gene ((tang min) OR (chang min)) ((jeong ghi) OR (hong ghi)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang ya) or (yang xi))ng ya hua gene ((tang min) OR (chang min)) ((jeong ghi) or (hong ghi)) ;".
• Adding a wildcard symbol may retrieve word variants: ((yang ya) or (yang xi))ng ya hua gene ((tang min) OR (chang min)) ((jeong ghi) or (hong ghi)) ;*.
