Perhaps you should try some spelling variations:
kang minh » kang minah, sang minh, anh minh
minh long » minh cong, vinh long
yang jie » yang di, yang jui, yang xi
yang jin » yang jun, ying jin, shang jin
yi kang » xi kang, yi gang, yi yang
long du » long d, long do, long run
wang » 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 OR wing) yan ((yang jie) or (yang jin)) yi kang minh long du ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) yan ((yang jie) OR (yang jin)) yi kang minh long du ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wing) yan ((yang jie) or (yang jin)) yi kang minh long du ;*".
