Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
van cham » van chat, van tham, va cham
te sach » toc sach
vu sach » vu bach, su sach, vu khach
lang xa » lang ha, dang xay, lang van
hanh di » hanh vi, hanh de, hang di
y lang » o lang, _ lang, tay lang
soc va » hoc va, doc va, goc va
loc va » hoc va, luc va
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) OR (vu sach)) y lang xa hoi. hieu van cham ((soc va) OR (loc va)) hanh di cua vat~.
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (vu sach)) y lang xa hoi. hieu van cham ((soc va) or (loc va)) hanh di cua vat*.
