Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
ve triet » va trien, su triet
xay hoi » tay hoi, cay phoi, gay thoi
hieu va » lieu va, hieu qua
xuc van » duc van, luc van, vuc van
hanh di » hanh vi, hanh de, hang di
ban ky » dan ky
va cam » va cham, va cac, va cao
di ve » dai ve, de ve, do ve

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 ((ban ky) OR (van ky)) dang ((xay hoi) OR (xa hoi)). hieu va cam xuc van hanh di ve triet~.
• Adding a wildcard symbol may retrieve word variants: tu ((ban ky) or (van ky)) dang ((xay hoi) or (xa hoi)). hieu va cam xuc van hanh di ve triet*.
