Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang hua » wang hua, yang hui, ying hua
yang jui » yang judy, yang di, yang xi
gene yan » gene bank, ren yan, see yan
won sacu » von sach, wong sau
non sacu » union sacu, non same, non sans
yan ji » yan jiu, ban ji, pan ji

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

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