Perhaps you should try some spelling variations:
human gene » human genome, human gender, human bone
yuan kang » yuan wang, yuan chang, chan kang
hua gene » a gene, hua ren, hy5 gene
yang lin » yang jin, wang lin, yang li
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
yan tao » wang tao
wang » wing, wan, 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 yan tao ((hua gene) OR (human gene)) ((yuan kang) OR (yang lin)) ((hong ghi) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan tao ((hua gene) OR (human gene)) ((yuan kang) or (yang lin)) ((hong ghi) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan tao ((hua gene) OR (human gene)) ((yuan kang) or (yang lin)) ((hong ghi) or (hong hai)) ;*.
