Perhaps you should try some spelling variations:
wong shiu » cong shu, song shin, wong sau
yang yao » yang yang, wang yan, yang yi
test sat » test salt, test set, test sit
sat minh » sang minh, sato mine, st min
wong siu » kong siu, wong sau, wong siew
yang ka » yang fan
long du » long d, long do, long run

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

• Performing a fuzzy search may retrieve terms with similar spellings: dong ((yang ka) or (yang yao)) a test sat minh ((long du) or (((wong siu) OR (wong shiu)))) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang ka) OR (yang yao)) a test sat minh ((long du) OR (((wong siu) OR (wong shiu)))) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang ka) or (yang yao)) a test sat minh ((long du) or (((wong siu) OR (wong shiu)))) ;*".
