Perhaps you should try some spelling variations:
truc van » truc va, thuc van, truc ban
sach ty » sach tu, sach thu, xach tay
xang xa » lang xa, mang xa, ang xa
hieu va » lieu va, hieu qua
tuc van » thuc van, tuc va, duc van
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) xang xa hoi. hieu va cam ((tuc van) OR (truc van)) hanh vi cuu tre~.
• 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) OR (truc 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) OR (truc van)) hanh vi cuu tre*.
