Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan yang » dan yang, yin yang
sang minh » kang minah, anh minh, song min
tang min » chang min, yang mind, tang li
wong siu » wong shiu, kong siu, wong sau
yang li » yang lin, yang di, yang xi
li wu » l wu, yi wu, li ju

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yidan yang li wu ((tang min) OR (sang minh)) wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yidan yang li wu ((tang min) OR (sang minh)) wong siu ;*.
