Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van nang » van quang, van ban, van dong
vu sach » vu bach, su sach, vu khach
hieu va » lieu va, hieu qua
xuc ban » duc ban, cuc ban, quoc ban
hang vi » hang va, hang di, khang voi
v nang » va nang, vu nang, voi nang
va cam » va cham, va cac, va cao

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: vu sach ((v nang) OR (van nang)) xa hoi. hieu va cam xuc ban ((hang vi) OR (hanh vi)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((v nang) OR (van nang)) xa hoi. hieu va cam xuc ban ((hang vi) or (hanh vi)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: vu sach ((v nang) OR (van nang)) xa hoi. hieu va cam xuc ban ((hang vi) or (hanh vi)) cua triet*.
