Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
su sach » so sach, vu sach
bo sach » co sach, hoc sach
van cac » van hac, van cau, van bac
cac tuc » cac toc, cac tu, cac tac
xa danh » va danh, dia danh, nam danh
danh vi » hanh vi, dinh vi, danh di
y nang » ky nang, ly nang, v nang
vi cua » vai cua, di cua
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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: ((su sach) OR (bo sach)) y nang x hoi. hieu van cac tuc xa danh vi cua te~.
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (bo sach)) y nang x hoi. hieu van cac tuc xa danh vi cua te*.
