Perhaps you should try some spelling variations:
gene sang » lee sang, gene bank
sang minh » kang minah, anh minh, song min
yang jui » yang judy, yang di, yang xi
hua gene » human gene, a gene, hua ren
wong sau » wong sam, wong siu, wong shiu
hong hai » shang hai, zhong tai, dang hai
yang yi » yang di, yang xi
hong 7 » hong w, hong a, hong g

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yi) OR (yang jui)) ya hua gene sang minh ((wong sau) or (((hong hai) or (hong 7)))) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yi) OR (yang jui)) ya hua gene sang minh ((wong sau) OR (((hong hai) OR (hong 7)))) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yi) OR (yang jui)) ya hua gene sang minh ((wong sau) or (((hong hai) or (hong 7)))) ;*".
