Perhaps you should try some spelling variations:
thi nang » thi cong, ki nang, thi hanh
hanh vai » hanh vi, hanh va, hanh tai
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
xac hoi » xa hoi, cac thoi, cac khoi
sac ly » sac ky
loc va » luc va
va xac » va cac
tu sac » tu sach, tu cac, tu san

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 ly va xac hoi. ((hieu ve) OR (thi nang)) cau ((loc va) OR (hoc va)) hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ly va xac hoi. ((hieu ve) or (thi nang)) cau ((loc va) OR (hoc va)) hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ly va xac hoi. ((hieu ve) or (thi nang)) cau ((loc va) OR (hoc va)) hanh vai cua tre*.
