Perhaps you should try some spelling variations:
dang tay » dang xay, dung tay, dan tay
hieu van » hieu va, thien van, lieu va
te sach » toc sach
sach ty » sach y, sach tu, sach thu
ty dang » ty xang, ky dang, ty hang
tay hoi » tay ho, tao hoi, tay thai
van lam » van nam
cua tre » cua te, cuu tre, cua triet
luc va » tuc va, loc va
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: te sach ty dang tay hoi. hieu van lam ((luc va) OR (duc va)) hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach ty dang tay hoi. hieu van lam ((luc va) or (duc va)) hanh vi cua tre*.
