hua gene » human gene, a gene, hua ren
yang jin » yang jie, yang jun, ying jin
wong sau » wong sam, wong siu, wong shiu
yang xi » yang di, yang yi, yang jui
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((hyoung yan) OR (hyoung gun)) hua gene ((yang jin) or (yang xi)) wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((hyoung yan) OR (hyoung gun)) hua gene ((yang jin) OR (yang xi)) wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((hyoung yan) OR (hyoung gun)) hua gene ((yang jin) or (yang xi)) wong sau ;*".
