shang hai » shang kai, dang hai, chang ha
hua gene » human gene, a gene, hua ren
hong hai » zhong tai, dang hai, hong tan

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

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