Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
hieu vien » hieu hien, thieu nien, hieu tieng
hanh lam » thanh lap, hanh kem, hanh va
van hanh » van thanh, ban hanh, van anh
cua tre » cua te, cuu tre, cua triet
lam cua » nam cua, lam chat
xuc van » duc van, luc van, vuc van
cac xuc » cam xuc, cac nuoc, chat xuc
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ma hoi » mai hoi, ma hoa, me hoi

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 ((ma hoi) OR (xa hoi)). ((hieu vien) OR (hieu viec)) cac xuc van hanh lam cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ((ma hoi) or (xa hoi)). ((hieu vien) OR (hieu viec)) cac xuc van hanh lam cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ((ma hoi) or (xa hoi)). ((hieu vien) OR (hieu viec)) cac xuc van hanh lam cua tre*.
