Perhaps you should try some spelling variations:
sach vay » sach va, sach hay, sach nay
ban hanh » ban hang
cua tre » cua te, cua triet, dua tren
hanh di » hanh vi, hanh de, hang di
xuc ban » duc ban, cuc ban, quoc ban
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
cuu tre » cau tren, cau treo
ve cac » va cac, vien cac

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 vay) OR (sach y)) nang xa hoi. hieu ve cac xuc ban hanh di ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach vay) or (sach y)) nang xa hoi. hieu ve cac xuc ban hanh di ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: te ((sach vay) or (sach y)) nang xa hoi. hieu ve cac xuc ban hanh di ((cua tre) OR (cuu tre))*.
