Perhaps you should try some spelling variations:
kang minah » sang minh
kang minh » sang minh, anh minh, kan min
wang yang » wang yan, wang liang, wang yanling
yang jun » yang jui, pang jun, yang jin
yang jie » yang jin, yang di, yang jui
wai yan » wang yan, wei yang
long du » long d, long do, long run

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

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