Perhaps you should try some spelling variations:
zhang yan » zhang fan, zhang jian, wang yan
yang jie » yang jin, yang di, yang jui
ying jin » yang jin, jing ji
kong siu » kong eiu, kong sar, gong si
wong siu » wong shiu, wong sau, wong siew
ku ying » ka ying, ku ring, hui ying
limin » limit, lixin
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: zhang yan ((yang jie) or (wang limin)) ku ying jin ((((kong siu) OR (wong siu))) or (dong sin)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: zhang yan ((yang jie) OR (wang limin)) ku ying jin ((((kong siu) OR (wong siu))) OR (dong sin)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yan ((yang jie) or (wang limin)) ku ying jin ((((kong siu) OR (wong siu))) or (dong sin)) ;*".
