yang min » yang mind, tang min, yang lin
yang jin » yang jie, yang jun, ying jin
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
hua ren » hua chen
yng ya » yang yao

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

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