Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
tu cach » tu cac
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
cac xuc » cac nuoc, chat xuc, cac cuoc
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: ((tu cach) OR (tu sach)) ky nang x hoi. hieu ve ((cac xuc) OR (cam xuc)) van hanh vi cua te~.
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (tu sach)) ky nang x hoi. hieu ve ((cac xuc) or (cam xuc)) van hanh vi cua te*.
