Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
ban hanh » ban hang
van hanh » van thanh, van anh, van ban
su sach » so sach, vu sach
hieu va » lieu va, hieu qua
cau xuc » cam xuc, cau luc, cau truc
va hanh » va thanh, va danh, dao hanh
doi cua » dai cua, hoi cua
sach v » sach va, sach y, sach 2
v nang » va nang, vu nang, van nang
va cau » van cau, va cac, va dau
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 cau xuc ((((va hanh) OR (ban hanh))) OR (van hanh)) doi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang x hoi. hieu va cau xuc ((((va hanh) OR (ban hanh))) or (van hanh)) doi cua triet~".
• Adding a wildcard symbol may retrieve word variants: su sach v nang x hoi. hieu va cau xuc ((((va hanh) OR (ban hanh))) or (van hanh)) doi cua triet*.
