Perhaps you should try some spelling variations:
sach tham » sach nha
te sach » toc sach
bang xa » bang va, mang xa, ang xa
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
xuc van » duc van, luc van, vuc van
hanh di » hanh vi, hanh de, hang di
ve cac » va cac, vien cac
di cua » dai cua, doi cua, de cua
cua cu » cua chu, cua cau, cua su

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 tham ((bang xa) OR (lang xa)) hoi. hieu ve cac ((xuc van) OR (duc tan)) hanh di cua cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tham ((bang xa) OR (lang xa)) hoi. hieu ve cac ((xuc van) or (duc tan)) hanh di cua cu~".
• Adding a wildcard symbol may retrieve word variants: te sach tham ((bang xa) OR (lang xa)) hoi. hieu ve cac ((xuc van) or (duc tan)) hanh di cua cu*.
