hieu va » lieu va, hieu qua
dinh vi » dinh ve, dinh viet, dinh tri

va lam » van lam, va lap
xuc va » tuc va, luc va, xac va

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((te bai) or (te tai)) ky lang xa hoi. hieu va lam ((xuc va) OR (duc va)) dinh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te bai) OR (te tai)) ky lang xa hoi. hieu va lam ((xuc va) OR (duc va)) dinh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te bai) or (te tai)) ky lang xa hoi. hieu va lam ((xuc va) OR (duc va)) dinh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: ((te bai) or (te tai)) ky lang xa hoi. hieu va lam ((xuc va) OR (duc va)) dinh vi cua triet*.
