Perhaps you should try some spelling variations:
human gene » human genome, human gender, human bone
yang yao » yang yang, wang yan, yang fan
hua gene » a gene, hua ren, hy5 gene
hong ghi » zhong zhi, hong g, hong hai
yang ya » yang ka, yang y, yang yang
yang yi » yang di, yang xi, yang jui
li hong » le hong, li cong, li rong

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang ya) OR (yang yao))) or (yang yi))ng ya ((hua gene) or (human gene)) tang li hong ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang ya) OR (yang yao))) OR (yang yi))ng ya ((hua gene) OR (human gene)) tang li hong ghi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang ya) OR (yang yao))) or (yang yi))ng ya ((hua gene) or (human gene)) tang li hong ghi ;".
• Adding a wildcard symbol may retrieve word variants: ((((yang ya) OR (yang yao))) or (yang yi))ng ya ((hua gene) or (human gene)) tang li hong ghi ;*.
