dong yang » dong hoang, wang yang, yang yang
gene pang » gene bank, gene part
yang zhi » wang zhi, yan zhi, liang zhi
zhi gene » i gene, iii gene
pang jun » yang jui
wong sau » wong sam, wong siu, wong shiu

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: wang dong yang zhi gene pang jun ((wong sau) OR (kong (sar OR sara))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang dong yang zhi gene pang jun ((wong sau) or (kong (sar or sara))) ;*.
