Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
thanh vi » hanh vi, thanh va, thanh ve
va thanh » gia thanh, ban thanh, va tinh
tang ma » mang may, tang van
ky tang » ky nang, ky dang, kho tang
hieu va » lieu va, hieu qua
hieu ve » hieu van
dam tu » nam tu, cam tu, tam tu
ma hoi » mai hoi, xa hoi, ma hoa

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) OR (hieu va)) dam tu va thanh vi ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky tang ma hoi. ((hieu ve) OR (hieu va)) dam tu va thanh vi ((cua triet) or (su triet))~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky tang ma hoi. ((hieu ve) OR (hieu va)) dam tu va thanh vi ((cua triet) or (su triet))*.
