Perhaps you should try some spelling variations:
liu yang » liu ying, lijun yang, liu yaning
liu ming » liu ying, liu jin, qu ming
lu minh » le minh, lu ninh, u minh
tu minh » thu minh, thi minh, duc minh
vu minh » van minh
vu dinh » quy dinh
liberation » deliberation, vibration, iteration

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((liu ming) or (((lu minh) OR (tu minh))))) or (((((vu minh) or (vu dinh))) or (liu yang)))) (people's liberation _)~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((liu ming) OR (((lu minh) OR (tu minh))))) OR (((((vu minh) OR (vu dinh))) OR (liu yang)))) (people's liberation _).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((liu ming) or (((lu minh) OR (tu minh))))) or (((((vu minh) or (vu dinh))) or (liu yang)))) (people's liberation _)".
• Adding a wildcard symbol may retrieve word variants: ((((liu ming) or (((lu minh) OR (tu minh))))) or (((((vu minh) or (vu dinh))) or (liu yang)))) (people's liberation _)*.
