Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan yang » dan yang, yin yang
chang mae » chang ha, changes made
chan ming » kian ming, chan eng, chan fong
kang min » kan min, tang min, kang minah
wong sau » wong sam, wong siu, wong shiu
di lu » li lu, yi lu

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: wang yidan yang di lu ((kang min) OR (((chang mae) OR (chan ming)))) wong sau ;~.
• Adding a wildcard symbol may retrieve word variants: wang yidan yang di lu ((kang min) or (((chang mae) or (chan ming)))) wong sau ;*.
