Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » thien van, lieu va, hieu ve
hanh dai » hanh tai, hanh dao, vanh dai
tu sach » thu sach, su sach, te sach
cao hoi » cau hoi, co hoi, cao hoc
hieu va » lieu va, hieu qua
cau xuc » cam xuc, cau luc, cau truc
va hanh » van hanh, va thanh, va danh
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va

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 cao hoi. ((hieu van) OR (hieu va)) cau xuc va hanh dai cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang cao hoi. ((hieu van) or (hieu va)) cau xuc va hanh dai cua triet*.
