Perhaps you should try some spelling variations:
chan kang » chung kang, chan eng, chan fong
chia chen » china chen, chia wen, hua chen
yan wang » yuan wang, yang yang, qian wang
tan chia » tuan china, than china, can china
yang jui » yang di, yang xi, yang yi
yu wang » yue wang, yu fang, yu gang
hong yu » wong yue

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: ((((yu wang) OR (yan wang))) OR (chan kang)) tan chia chen ((yang jui) OR (yang judy)) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yu wang) or (yan wang))) or (chan kang)) tan chia chen ((yang jui) OR (yang judy)) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yu wang) or (yan wang))) or (chan kang)) tan chia chen ((yang jui) OR (yang judy)) hong yu ;*.
