Perhaps you should try some spelling variations:
chen yulan » chen yugang, chen yulu, chen yun
dong yang » dong hoang, wang yang, yang yang
mun leong » min jeong
leong wai » leong lap
dong nan » dong sin, dong cao
dong bin » dong sin, dong di, dann bin
yet a » et a, yet _, get a
ye a » e a, me a, y a

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((dong nan) OR (dong yang))) or (dong bin)) ((ye a) or (yet a)) chen yulan mun leong wai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong nan) OR (dong yang))) OR (dong bin)) ((ye a) OR (yet a)) chen yulan mun leong wai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong nan) OR (dong yang))) or (dong bin)) ((ye a) or (yet a)) chen yulan mun leong wai ;".
• Adding a wildcard symbol may retrieve word variants: ((((dong nan) OR (dong yang))) or (dong bin)) ((ye a) or (yet a)) chen yulan mun leong wai ;*.
