Perhaps you should try some spelling variations:
yang jin » yang jie, yang jun, ying jin
hua gene » human gene, a gene, hy5 gene
yang min » yang mind, tang min, yang lin
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
yang li » yang lin, yang di, yang xi
hua ren » hua chen

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

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