Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
tu sach » thu sach, su sach, te sach
van cau » van dau, van hau, van chat
cau xuc » cam xuc, cau luc, cau truc
va lanh » va lang, va danh, va hanh
dao cua » dai cua, day cua, dan cua
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van 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) OR (v nang)) xa hoi. hieu van cau xuc va lanh dao cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (v nang)) xa hoi. hieu van cau xuc va lanh dao cua triet*.
