te sach » toc sach
hieu va » lieu va, hieu qua
cam tuc » cam xuc, cam tu, nam thuc

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 ((y lang) OR (_ lang)) xa hoi. hieu va cam tuc van anh vi cau treo~.
• Adding a wildcard symbol may retrieve word variants: te sach ((y lang) or (_ lang)) xa hoi. hieu va cam tuc van anh vi cau treo*.
