Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
cua tre » cua te, cuu tre, cua triet
truc va » thuc va, thuc vat, trung va
hieu va » lieu va, hieu qua
mai hoi » mai khoi, dai hoi, lai hoi
va cam » va cham, va cac, va cao
tuc va » thuc va, tuc xa, duc va
vi cua » vai cua, di cua
tu cao » cu cao, tu cac, vu cao

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 cao ky nang ((mai hoi) OR (ma hoa)). hieu va cam ((tuc va) OR (truc va)) thanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu cao ky nang ((mai hoi) or (ma hoa)). hieu va cam ((tuc va) or (truc va)) thanh vi cua tre*.
