Perhaps you should try some spelling variations:
wang yidan » wang yan
yidan yang » dan yang, yin yang
yang cindy » yang mind
sang minh » kang minah, anh minh, song min
yang jin » yang jie, yang jun, ying jin
wong yue » wang yue, hong yu
lin li » ling li, yin li, lin ling

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yidan yang ((lin li) OR (lin yi)) ((((sang minh) or (yang cindy))) or (yang jin)) wong yue ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yidan yang ((lin li) OR (lin yi)) ((((sang minh) OR (yang cindy))) OR (yang jin)) wong yue ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yidan yang ((lin li) OR (lin yi)) ((((sang minh) or (yang cindy))) or (yang jin)) wong yue ;".
• Adding a wildcard symbol may retrieve word variants: wang yidan yang ((lin li) OR (lin yi)) ((((sang minh) or (yang cindy))) or (yang jin)) wong yue ;*.
