Perhaps you should try some spelling variations:
weng fang » jing fang, wen wang
gene dang » genre dans
gene bank » gene banks, one bank, genomen bank
wei wang » wei yang, wen wang, wei shang
pang jun » yang jui
kai wong » kai hong, kai fang, kie wong
wong sau » wong sam, wong siu, wong shiu
yang xi » yang di, yang yi, yang jui

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wei wang) OR (weng fang)) ((pang jun) OR (yang xi)) ((gene dang) OR (gene bank)) kai wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wei wang) or (weng fang)) ((pang jun) or (yang xi)) ((gene dang) OR (gene bank)) kai wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((wei wang) or (weng fang)) ((pang jun) or (yang xi)) ((gene dang) OR (gene bank)) kai wong sau ;*.
