Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
lisa sang » lisa ann, lisa ring
tan yang » dan yang, tan ying, tan yong
li lisa » li lina, lind lisa, li linda
cong du » cong shu, cong sun
long du » long d, long do, long run
h yang » _ yang, hui yang

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 ((h yang) OR (tan yang)) li lisa sang minh ((cong du) OR (long du)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((h yang) or (tan yang)) li lisa sang minh ((cong du) OR (long du)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((h yang) or (tan yang)) li lisa sang minh ((cong du) OR (long du)) ;*.
