Perhaps you should try some spelling variations:
xay hoi » xa hoi, tay hoi, cay phoi
hieu va » hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
luu tre » luu tru, cuu tre, luy tre
va xay » va xac
vi luu » vi lua
ky va » ly va, ke va, my va

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 va xay hoi. ((hieu va) OR (lieu va)) cac xuc ((va hanh) OR (va danh)) vi luu tre~.
• Adding a wildcard symbol may retrieve word variants: tu cac ky va xay hoi. ((hieu va) or (lieu va)) cac xuc ((va hanh) or (va danh)) vi luu tre*.
