Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
trung van » truong van, trong van, trung va
ba trung » tai trung, nam trung, do trung
van hanh » van thanh, ban hanh, van anh
hanh vai » hanh vi, hanh va, hanh tai

hieu va » hieu qua
vai cua » dai cua, hai cua, lai cua

x hoi » xa hoi, o hoi, x ho

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: su sach v nang x hoi. ((hieu va) OR (lieu va)) ba trung van hanh vai cua triet~.
• Adding a wildcard symbol may retrieve word variants: su sach v nang x hoi. ((hieu va) or (lieu va)) ba trung van hanh vai cua triet*.
