Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan yang » dan yang, yin yang
chang min » zhang ming, chang mae, chan ming
kang min » kan min, tang min, kang minah
wong sau » wong sam, wong siu, wong shiu
yang li » yang lin, yang di, yang xi
li lu » li ju, li l, li li

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