Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
va cham » va chat, va tham
hieu va » lieu va, hieu qua
su sach » so sach, vu sach
cua tre » cua te, cuu tre, cua triet
y hang » ly hang, ty hang, yu hang
luc va » duc va, loc va
tuc va » thuc va, truc va, tuc xa
ma hoi » mai hoi, ma hoa, me hoi
vi cua » vai cua, di cua

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: su sach y hang ((ma hoi) OR (xa hoi)). hieu va cham ((luc va) OR (tuc va)) thanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: su sach y hang ((ma hoi) or (xa hoi)). hieu va cham ((luc va) or (tuc va)) thanh vi cua tre*.
