Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
toc sach » hoc sach, doc sach, thuoc sach
hanh vai » hanh vi, hanh va, hanh tai
van hanh » van thanh, ban hanh, van anh
lang van » dang van, tang van, hoang van
vai cua » dai cua, hai cua, lai cua
tuc van » thuc van, truc van, tuc va
cam tuc » cam xuc, cam tu, nam thuc
van cam » van nam, van lam, van cau
lang xa » lang ha, dang xay
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) OR (toc sach)) y ((lang xa) OR (lang van)) hoi. hieu van cam tuc van hanh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) y ((lang xa) or (lang van)) hoi. hieu van cam tuc van hanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) y ((lang xa) or (lang van)) hoi. hieu van cam tuc van hanh vai cua te*.
