Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh de » hanh ve, hanh kem
hanh di » hanh vi, hang di, danh di
cac xuc » cam xuc, cac nuoc, chat xuc
van hoc » van hoa
van hoi » van hoa, van hoe, van loi
ky dang » ky nang, ky danh
xac ky » cac ky, sac ky, bac ky
xuc va » duc va, tuc va, luc va
su xac » pu xac, su cac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su xac ky dang ((van hoi) OR (van hoc)). lieu va cac xuc va ((hanh di) or (hanh de)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky dang ((van hoi) OR (van hoc)). lieu va cac xuc va ((hanh di) OR (hanh de)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky dang ((van hoi) OR (van hoc)). lieu va cac xuc va ((hanh di) or (hanh de)) cua triet".
• Adding a wildcard symbol may retrieve word variants: su xac ky dang ((van hoi) OR (van hoc)). lieu va cac xuc va ((hanh di) or (hanh de)) cua triet*.
