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
y nang » ky nang, ly nang, v nang
xuc va » duc va, xac va
luc va » duc va, loc va
tuc va » thuc va, truc va, tuc xa
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 (luc va))) OR (tuc va)) hanh dai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. thien van dau ((((xuc va) OR (luc va))) or (tuc 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 (luc va))) or (tuc va)) hanh dai cua triet*.
