Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va thanh » gia thanh, ban thanh, va tinh
thanh vi » hanh vi, thanh va, thanh ve
va triet » va thiet, va trien, ve triet
ky tang » ky nang, ky dang, kho tang
tang ma » mang may, tang van
ma hoi » mai hoi, xa hoi, ma hoa
ve dam » ven dam, ke dam, ve dao
va dam » van dam, va dao, va dau

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky tang ma hoi. hieu ((ve dam) OR (va dam)) tu va thanh vi ((cua triet) OR (va triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky tang ma hoi. hieu ((ve dam) or (va dam)) tu va thanh vi ((cua triet) OR (va triet))~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky tang ma hoi. hieu ((ve dam) or (va dam)) tu va thanh vi ((cua triet) OR (va triet))*.
