Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan yang » dan yang, yin yang
chung kang » chan kang, chung kay, chung tong
chang ha » chang mae
wong siu » wong shiu, kong siu, wong sau
kan min » han min, kian ming, kyaw min
yi wu » yi xu
yi lu » yi xu, li 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 ((yi lu) OR (yi wu)) ((kan min) OR (((chang ha) OR (chung kang)))) wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yidan yang ((yi lu) OR (yi wu)) ((kan min) or (((chang ha) or (chung kang)))) wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yidan yang ((yi lu) OR (yi wu)) ((kan min) or (((chang ha) or (chung kang)))) wong siu ;*.
