Perhaps you should try some spelling variations:
thien van » thi van
cua triet » cua viet, su triet, va triet
hanh dai » hanh tai, hanh dao, vanh dai
tu sach » thu sach, su sach, te sach
van dau » van dao, phan dau
truc va » thuc va, thuc vat, trung va
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va
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: tu sach y nang x hoi. thien van dau ((xuc va) OR (truc va)) hanh dai cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. thien van dau ((xuc va) or (truc va)) hanh dai cua triet*.
