Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, ban hanh, van anh
hieu van » hieu va, thien van, lieu va
cac xuc » cam xuc, cac nuoc, chat xuc
cua tre » cua te, cuu tre, dua tren
hanh di » hanh vi, hanh de, hang di
xuc van » duc van, luc van, vuc van
ky lang » ky nang, ky dang, ky tang
lang ha » long ha
hieu ve » hieu va
ha hoi » hoa hoi, ha noi, xa 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 cac ky lang ha hoi. ((hieu ve) OR (hieu van)) cac xuc van hanh di ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky lang ha hoi. ((hieu ve) OR (hieu van)) cac xuc van hanh di ((cua tre) or (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky lang ha hoi. ((hieu ve) OR (hieu van)) cac xuc van hanh di ((cua tre) or (cua triet))*.
