Perhaps you should try some spelling variations:
ve triet » va trien, su triet
danh ve » dinh ve, hanh ve, anh ve
thuc va » thuc vat, thuc dan, thuc day
hieu va » lieu va, hieu qua
ky tang » ky dang, kho tang, ky trong
va cam » va cham, va cac, va cao
tuc va » truc va, tuc xa, duc va
te sac » te sach, te cac, te san
ve ve » de ve, va ve, ke ve

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 sac ((ky tang) OR (ky nang)) xa hoi. hieu va cam ((tuc va) OR (thuc va)) danh ve ve triet~.
• Adding a wildcard symbol may retrieve word variants: te sac ((ky tang) or (ky nang)) xa hoi. hieu va cam ((tuc va) or (thuc va)) danh ve ve triet*.
