Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
te sach » toc sach
sach ty » sach y, sach tu, sach thu
ty vang » ty xang, ty van, ly vang
vang xa » lang xa, mang xa, ang xa
ve cai » va cai, ve cac, ve tai
tuc va » thuc va, truc va, tuc xa
va dan » ca dan, va dao, va dau
dan de » dan den, dang de, van de
de cua » le cua, te cua, dieu cua
cua te » cua tu

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 vang xa hoi. hieu ((ve cai) OR (vien cac)) tuc va dan de cua te~.
• Adding a wildcard symbol may retrieve word variants: te sach ty vang xa hoi. hieu ((ve cai) or (vien cac)) tuc va dan de cua te*.
