Perhaps you should try some spelling variations:
viet cua » viec cua, viet ca, viet qua
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
tac van » tac vang, cac van, tac va
sat van » sat va, hat van, hoat van
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
cua tu » cua tuc, cua su, cua cu
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 sac ky nang x hoi. hieu vu cham ((tac van) OR (sat van)) anh viet cua tu~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang x hoi. hieu vu cham ((tac van) or (sat van)) anh viet cua tu*.
