Perhaps you should try some spelling variations:
yang ying » yang yang, yang jing, huang ying
wang yang » wang yan, wang liang, wang yanling
gene sang » lee sang, gene bank
sang minh » kang minah, anh minh, song min
hua gene » human gene, a gene, hua ren
hong shu » cong shu, tong shui, wong shiu
hong ghi » zhong zhi, hong g, hong hai
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 ying) or (yang yi))) or (wang yang)) ya hua gene sang minh ((hong shu) OR (hong ghi)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang ying) OR (yang yi))) OR (wang yang)) ya hua gene sang minh ((hong shu) OR (hong ghi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang ying) or (yang yi))) or (wang yang)) ya hua gene sang minh ((hong shu) OR (hong ghi)) ;*".
