Perhaps you should try some spelling variations:
kang minah » sang minh
kang vinh » sang minh
yan yang » yang yang, yao yang, dan yang
yang jie » yang jin, yang di, yang jui
long ago » long arm
jie yi » jia yi
long d » long do, long du, long _
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yan yang jie yi ((kang vinh) OR (kang minah)) ((long ago) or (long d)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan yang jie yi ((kang vinh) OR (kang minah)) ((long ago) OR (long d)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yang jie yi ((kang vinh) OR (kang minah)) ((long ago) or (long d)) ;*".
