Perhaps you should try some spelling variations:
zhang yin » zhang ying, zhang xin, zhang jin
zhang yan » zhang fan, zhang jian, wang yan
john kong » john king, john wong, john bonn
john song » john wong, john bonn, john ngosong
yang lin » yang jin, wang lin, yang liang
yang li » yang di, yang xi, yang yi
ku ying » ka ying, ku ring, hui ying

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: ((zhang yin) OR (zhang yan)) ((yang li) OR (yang lin)) ku ying ((john kong) OR (john song)) siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang yin) or (zhang yan)) ((yang li) or (yang lin)) ku ying ((john kong) OR (john song)) siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((zhang yin) or (zhang yan)) ((yang li) or (yang lin)) ku ying ((john kong) OR (john song)) siu ;*.
