Perhaps you should try some spelling variations:
cuu tre » cau tren, cau treo
ky lang » ky nang, ky dang, ky tang
lang ha » long ha
cua tre » cua te, cua triet, dua tren
hieu va » lieu va, hieu qua
va tham » van tham, va cham, va thanh
doc va » duoc va, hoc va, duc va
te ban » te bao
ban ky » van ky, dan ky
ha hoi » hoa hoi, ha noi, xa hoi
soc va » hoc va, loc va, goc 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: te ban ky lang ha hoi. hieu va tham ((soc va) OR (doc va)) hanh vi ((cua tre) OR (cuu tre))~.
• Adding a wildcard symbol may retrieve word variants: te ban ky lang ha hoi. hieu va tham ((soc va) or (doc va)) hanh vi ((cua tre) or (cuu tre))*.
