Perhaps you should try some spelling variations:
dua tren » dung tren
cham tuc » nham thuc, pham thuc, tham thuc
xa hanh » xa thanh, xa khanh, va hanh
vu cham » va cham, vu kham, tu cham
sach tu » sach thu, sach ty, sach uu
hieu vu » hieu va, hieu ve, hieu su
lang xa » lang ha, dang xay, lang van
cach tu » cach thuc
cuu tre » cua tre, cau tren, cau treo

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 tu) OR (cach tu)) lang xa hoi. hieu vu cham tuc xa hanh vi ((dua tren) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tu) OR (cach tu)) lang xa hoi. hieu vu cham tuc xa hanh vi ((dua tren) or (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach tu) OR (cach tu)) lang xa hoi. hieu vu cham tuc xa hanh vi ((dua tren) or (cuu tre))*.
