Perhaps you should try some spelling variations:
cau tren » cu tren, dau tren, ca tren
cuu tre » cua tre, cau treo
van anh » van thanh, tuan anh, van minh
tuc van » thuc van, truc van, tuc va
te sach » toc sach
hieu va » lieu va, hieu qua
cam tuc » cam xuc, cam tu, nam thuc
va cam » va cham, va cac, va cao
y lang » o lang, tay lang, yen lang
_ lang » o lang, _ land
anh vi » hanh vi, anh va, anh ve

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 ((cuu tre) OR (cau tren))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y lang) or (_ lang)) xa hoi. hieu va cam tuc van anh vi ((cuu tre) OR (cau tren))~".
• Adding a wildcard symbol may retrieve word variants: te sach ((y lang) or (_ lang)) xa hoi. hieu va cam tuc van anh vi ((cuu tre) OR (cau tren))*.
