Perhaps you should try some spelling variations:
wang liang » wang yang
wang wang » wang yang, wang yan, wang yong
wong sau » wong siu, wong shiu, kong sar
wong sam » kong sar, von sam, wong max
un tant » en tant
tant li » tang li, tan li
yan di » yang di, pan di, yan zi
di un » de un

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang wang) or (wang liang)) yan di un tant li ((((wong sau) OR (wong lai))) or (wong sam)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang liang)) yan di un tant li ((((wong sau) OR (wong lai))) OR (wong sam)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang liang)) yan di un tant li ((((wong sau) OR (wong lai))) or (wong sam)) ;*".
