Perhaps you should try some spelling variations:
chan kang » chung kang, chan eng, chan fong
kang chen » chang chen, jane chen, kang han
china won » china women, china wang, china why
china who » china why, china what
yang thi » dang thi, yang chik, yang di
thi hong » tan hong
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: chan kang chen ((((china won) OR (china who))) OR (ching kwan)) yang thi hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chan kang chen ((((china won) OR (china who))) or (ching kwan)) yang thi hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: chan kang chen ((((china won) OR (china who))) or (ching kwan)) yang thi hong yu ;*.
