Perhaps you should try some spelling variations:
yang jui » yang judy, yang di, yang yi
chan eng » chan fong, chan kang, chan ming
wong siu » wong shiu, kong siu, wong sau
wan yan » wang yan, nan yan, wai yan
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi
wu chan » w chan, wu chao, mun chan

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: wan yan ((yang li) OR (((yang jui) OR (yang xi)))) wu chan eng ((wong siu) OR (cong shu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((yang li) or (((yang jui) OR (yang xi)))) wu chan eng ((wong siu) or (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ((yang li) or (((yang jui) OR (yang xi)))) wu chan eng ((wong siu) or (cong shu)) ;*.
