Perhaps you should try some spelling variations:
qua phan » cua phan, qua than, quang phan
van hanh » van thanh, van anh, van ban
ban hanh » ban hang
va hanh » va thanh, va danh, dao hanh
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 qua phan tu ((((va hanh) OR (van hanh))) OR (ban hanh)) vai cua cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky nang x hoi. hieu qua phan tu ((((va hanh) OR (van hanh))) or (ban hanh)) vai cua cu~".
• Adding a wildcard symbol may retrieve word variants: tu van ky nang x hoi. hieu qua phan tu ((((va hanh) OR (van hanh))) or (ban hanh)) vai cua cu*.
