Perhaps you should try some spelling variations:
te sach » toc sach
sach ty » sach y, sach tu, sach thu
sang ma » tang ma, nang ma, sang tao
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
cac duc » cac du, cao duc, cac dac
va tinh » may tinh
tinh vi » trinh vi, tinh voi, tinh va
cua tre » cua te, cuu tre, cua triet
ve cac » va cac, vien cac
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 ((sang ma) OR (lang xa)) hoi. hieu ve cac duc va tinh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach ty ((sang ma) or (lang xa)) hoi. hieu ve cac duc va tinh vi cua tre*.
