Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
quoc ban » quoc bao, quoc lan, quoc quan
hanh tai » thanh tai, hang tai, han tai
va triet » va thiet, va trien, ve triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
va cham » va chat, va tham
xuc van » duc van, luc van, vuc van
tu dan » tuc dan, tu ban, cu dan
dan ky » van ky

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 dan ky lang xa hoi. lieu va cham ((xuc van) OR (quoc ban)) hanh tai ((cua triet) OR (va triet))~.
• Adding a wildcard symbol may retrieve word variants: tu dan ky lang xa hoi. lieu va cham ((xuc van) or (quoc ban)) hanh tai ((cua triet) or (va triet))*.
