Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
sach ty » sach tu, sach thu, xach tay
xang xa » lang xa, mang xa, ang xa
hieu va » lieu va, hieu qua
cam tuc » cam xuc, cam tu, nam thuc
tuc van » thuc van, truc van, tuc va
cuu tre » cua tre, cau tren, cau treo
va cam » va cham, va cac, va cao
vi cuu » vi luu, vinh cuu

You may be able to get more results by adjusting your search query.

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