Perhaps you should try some spelling variations:
gene yan » gene bank, ren yan, see yan
non sacu » union sacu, non same, non sans
yan hua » ya hua, wang hua, tuan hua
tan hua » tuan hua, wang hua, tan chia
won sau » wong sau, wong sam, wong siu
yan ji » yan jiu, ban ji, pan ji
wang » wing, wan, lang

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yan hua) OR (tan hua)) gene yan ji ((won sau) OR (non sacu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((yan hua) OR (tan hua)) gene yan ji ((won sau) OR (non sacu)) ;*.
