Perhaps you should try some spelling variations:
ying chan » ying chang, fong chan, jong chan
ying john » king john, young john, ying jin
wong shu » wong shiu, cong shu, wong siu
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
judy li » judy l
wang » wing, wan

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 OR lang) ying chan judy li ying john ((wong shu) OR (((wong sau) OR (wong sam)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ying chan judy li ying john ((wong shu) or (((wong sau) OR (wong sam)))) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ying chan judy li ying john ((wong shu) or (((wong sau) OR (wong sam)))) ;*.
