Perhaps you should try some spelling variations:
human gene » human genome, human gender, human bone
yao ying » yao yang, fan ying, ka ying
gao ying » yao yang, fan ying, ka ying
hua gene » a gene, hua ren, hy5 gene
law hong » law long, how hong, law ho
1 law » _ law, 1 la, a law
tan » than

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: (wan OR lang) ((yao ying) OR (gao ying)) ((hua gene) OR (human gene)) 1 law hong tan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or lang) ((yao ying) OR (gao ying)) ((hua gene) or (human gene)) 1 law hong tan ;~".
• Adding a wildcard symbol may retrieve word variants: (wan or lang) ((yao ying) OR (gao ying)) ((hua gene) or (human gene)) 1 law hong tan ;*.
