Perhaps you should try some spelling variations:
thien van » thi van
hanh tai » thanh tai, hang tai, han tai
hanh vai » hanh vi, hanh va, hanh van
cua tre » cua te, cuu tre, cua triet
cau luc » cau truc, cau phuc
hieu ve » hieu va, hieu van
xac hoi » xa hoi, cac thoi, cac khoi
sac ly » sac ky
luc va » duc va, tuc va, loc 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 (thien van)) cau luc va ((hanh vai) OR (hanh tai)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ly va xac hoi. ((hieu ve) or (thien van)) cau luc va ((hanh vai) OR (hanh tai)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ly va xac hoi. ((hieu ve) or (thien van)) cau luc va ((hanh vai) OR (hanh tai)) cua tre*.
