tang min » chang min, sang minh, yang mind
yang lin » yang jin, wang lin, yang li
hong ghi » zhong zhi, hong g, hong hai
chang ha » chang mae
yang ya » yang yao, yang ka, yang y
yang yi » yang di, yang xi, 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 yi))ng ya hua gene ((tang min) or (yang lin)) ((hong ghi) or (chang ha)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang ya) OR (yang yi))ng ya hua gene ((tang min) OR (yang lin)) ((hong ghi) OR (chang ha)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang ya) OR (yang yi))ng ya hua gene ((tang min) or (yang lin)) ((hong ghi) or (chang ha)) ;".
• Adding a wildcard symbol may retrieve word variants: ((yang ya) OR (yang yi))ng ya hua gene ((tang min) or (yang lin)) ((hong ghi) or (chang ha)) ;*.
