Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va thanh, va danh
hanh va » hang va, hanh vi
hieu ve » hieu van
xuc va » duc va, tuc va, luc va
dan y » dan ky, dan _, day y
san y » san _

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((san y) OR (dan y)) nang xa hoi. ((hieu ve) or (hieu va)) cam xuc va hanh va su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((san y) OR (dan y)) nang xa hoi. ((hieu ve) OR (hieu va)) cam xuc va hanh va su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((san y) OR (dan y)) nang xa hoi. ((hieu ve) or (hieu va)) cam xuc va hanh va su triet".
• Adding a wildcard symbol may retrieve word variants: thuat ((san y) OR (dan y)) nang xa hoi. ((hieu ve) or (hieu va)) cam xuc va hanh va su triet*.
