Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
yang minh » sang minh, yang mind, kang minah
yang jui » yang judy, yang di
tan yang » dan yang, tan ying, tan yong
yang yi » yang di
yang xi » yang di
long du » long d, long do, long did

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang hyoung ((((yang yi) OR (yang xi))) or (yang jui)) tan yang minh ((long run) or (long du)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang hyoung ((((yang yi) OR (yang xi))) OR (yang jui)) tan yang minh ((long run) OR (long du)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung ((((yang yi) OR (yang xi))) or (yang jui)) tan yang minh ((long run) or (long du)) ;*".
