Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
doanh van » doan van, doanh va, doanh ban
ky doanh » ly doanh, ky danh, ty doanh
hanh de » hanh ve, hanh kem
hanh di » hanh vi, hang di, danh di
so sach » so sanh, bo sach, co sach
sach ky » sac ky, sach y, sach ty
cau xuc » cam xuc, cau luc, chat xuc
van hoi » van hoa, van hoc, van hoe

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: so sach ky doanh van hoi. lieu va ((cau xuc) OR (cau truc)) va ((hanh di) OR (hanh de)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky doanh van hoi. lieu va ((cau xuc) OR (cau truc)) va ((hanh di) or (hanh de)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: so sach ky doanh van hoi. lieu va ((cau xuc) OR (cau truc)) va ((hanh di) or (hanh de)) cua triet*.
