Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
su sach » so sach, vu sach
va hanh » van hanh, va thanh, va danh
va cham » va chat, va tham
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac
vi cua » vai cua, di cua
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 y nang x hoi. hieu ((ve cac) OR (va cham)) tuc ((va hanh) OR (ban thanh)) vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: su sach y nang x hoi. hieu ((ve cac) or (va cham)) tuc ((va hanh) or (ban thanh)) vi cua tre*.
