yang amin » yang jin, yang mind
shang hai » shang kai, dang hai, hong hai
yang jui » yang judy, yang di, yang xi
yang lin » yang jin, wang lin, yang li
chang ha » chang mae
a gene » a genre, a gender, a gentle

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

• Performing a fuzzy search may retrieve terms with similar spellings: dong ((yang jui) or (yang yang)) a gene ((yang amin) OR (yang lin)) ((shang hai) or (chang ha)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang jui) OR (yang yang)) a gene ((yang amin) OR (yang lin)) ((shang hai) OR (chang ha)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang jui) or (yang yang)) a gene ((yang amin) OR (yang lin)) ((shang hai) or (chang ha)) ;".
• Adding a wildcard symbol may retrieve word variants: dong ((yang jui) or (yang yang)) a gene ((yang amin) OR (yang lin)) ((shang hai) or (chang ha)) ;*.
