Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
hanh noi » ha noi, hanh vi, nang noi
vu cham » va cham, vu kham, tu cham
xuc van » duc van, luc van, vuc van
noi cua » hoi cua, doi cua, moi cua
cua tre » cua te, cuu tre, cua triet
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
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: te sac ky nang x hoi. hieu ((ve cam) OR (vu cham)) xuc van hanh noi cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sac ky nang x hoi. hieu ((ve cam) or (vu cham)) xuc van hanh noi cua tre*.
