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

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~.
• 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*.
