Perhaps you should try some spelling variations:
union sacu » non sacu
wang dong » wang yong, wang hong, wang yang
dong yang » dong hoang, wang yang, yang yang
yang zhi » wang zhi, yan zhi, liang zhi
zhi west » ii west
yang jui » yang judy, yang di, yang yi
wong sau » wong sam, wong siu, wong shiu
yang xi » yang di, yang yi
won sau » wong sam, wong siu

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

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