Perhaps you should try some spelling variations:
song minh » sang minh, song min, gong min
song ming » song bing, song min, gong min
yang lin » yang jin, wang lin, yang liang
long shu » cong shu, tong shui, long du
yang li » yang di, yang yi, tang li
yang xi » yang di, yang yi, yang jui
wang » wing, wan, lang

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 yan ((((yang li) OR (yang lin))) OR (yang xi)) lu ((song minh) OR (song ming)) long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((yang li) or (yang lin))) or (yang xi)) lu ((song minh) OR (song ming)) long shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yang li) or (yang lin))) or (yang xi)) lu ((song minh) OR (song ming)) long shu ;*.
