hieu van » hieu va, thien van, lieu va
tu nang » tru nang, tu nong, tu nano
van cac » van hac, van cau, van bac
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » van hanh, va thanh, va danh
su cac » tu cac, su cao, su can

x hoi » xa hoi, o hoi, x ho

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

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