Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
va trien » va truyen, va thiet, va tuyen
va dinh » van dinh, va kinh, va tinh
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu ve » hieu van
hieu va » lieu va, hieu qua
dinh ve » dinh ket, dinh van
cam tuc » cam xuc, cam tu, nam thuc
te sai » te tai, te bai, te lai
tuc va » thuc va, truc va, tuc xa
sai ky » sac ky

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: te sai ky tang xa hoi. ((hieu ve) OR (hieu va)) cam tuc va dinh ve ((va trien) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky tang xa hoi. ((hieu ve) OR (hieu va)) cam tuc va dinh ve ((va trien) or (su triet))~".
• Adding a wildcard symbol may retrieve word variants: te sai ky tang xa hoi. ((hieu ve) OR (hieu va)) cam tuc va dinh ve ((va trien) or (su triet))*.
