Perhaps you should try some spelling variations:
te sach » toc sach
sach ky » sac ky, sach y, sach ty
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
qua cac » cua cac
cac toc » cac toi, cac nuoc, cac thoi
mat cua » ma cua, manh cua, mang cua
toc ta » toc tay, toc thai
ta van » tan van, tap van, va van

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 ky lang xa hoi. hieu qua cac toc ta van ((mat cua) OR (dai cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: te sach ky lang xa hoi. hieu qua cac toc ta van ((mat cua) or (dai cua)) tre*.
