Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
yang minh » yang mind, kang minah, anh minh
yang jun » yang jui, yang jin, yang judy
pang jun » yang jui
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: wai yan ((((yang jun) OR (pang jun))) or (yang jie)) yu ((yang minh) or (sang minh)) long du ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wai yan ((((yang jun) OR (pang jun))) OR (yang jie)) yu ((yang minh) OR (sang minh)) long du ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan ((((yang jun) OR (pang jun))) or (yang jie)) yu ((yang minh) or (sang minh)) long du ;*".
