Perhaps you should try some spelling variations:
ban hanh » ban hang
hieu ve » hieu va, hieu van
ve phan » va phan, ke phan, ve phat
va hanh » van hanh, va thanh, va danh
vai cua » dai cua, hai cua, lai cua
tu van » tu va
cua cu » cua chu, cua cau, cua su
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: tu van ky nang x hoi. hieu ve phan tu ((va hanh) OR (ban hanh)) vai cua cu~.
• Adding a wildcard symbol may retrieve word variants: tu van ky nang x hoi. hieu ve phan tu ((va hanh) or (ban hanh)) vai cua cu*.
