Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song ming
wang yao » wang yan, yang yao, gang yao
yang xin » yang jin, yang lin, zhang xin
song min » song ming, gong min, jong min
yang jie » yang jin, yang di, yang jui
jeong yu » jeong su, hong yu, jeong _
yang xi » yang di, yang yi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yao ((yang xi) or (yang xin)) li ((((sang minh) OR (song min))) or (yang jie)) jeong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yao ((yang xi) OR (yang xin)) li ((((sang minh) OR (song min))) OR (yang jie)) jeong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yao ((yang xi) or (yang xin)) li ((((sang minh) OR (song min))) or (yang jie)) jeong yu ;".
• Adding a wildcard symbol may retrieve word variants: wang yao ((yang xi) or (yang xin)) li ((((sang minh) OR (song min))) or (yang jie)) jeong yu ;*.
