Perhaps you should try some spelling variations:
thien van » thi van
tu sach » thu sach, su sach, te sach
anh doi » anh noi, anh doc, thanh doi
luc van » luoc van, luu van, duc van
cam luc » cam xuc, cau luc
van cam » van nam, van lam, van cau
sach ty » sach y, sach tu, sach thu
lang xa » lang ha, dang xay, lang van
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: tu sach ty ((mang may) OR (lang xa)) hoi. thien van cam luc van ((anh doi) OR (hanh vi)) cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((mang may) or (lang xa)) hoi. thien van cam luc van ((anh doi) or (hanh vi)) cua te*.
