Perhaps you should try some spelling variations:
gene yang » gene bank
hua gene » human gene, a gene, hua ren
yang jun » yang jui, pang jun, yang jin
hong 7hi » hong ghi, zhong zhi, hong hai
yan zhi » wang zhi
yan yi » yang yi, tan yi, yin yi
yan zi » yuan zi, ban zi
hong 7 » hong w, hong a, hong g
wang » wing, lang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) ((yan yi) OR (((yan zi) OR (yan zhi)))) hua gene yang jun ((hong 7) OR (hong 7hi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wan) ((yan yi) or (((yan zi) or (yan zhi)))) hua gene yang jun ((hong 7) or (hong 7hi)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wan) ((yan yi) or (((yan zi) or (yan zhi)))) hua gene yang jun ((hong 7) or (hong 7hi)) ;*.
