Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
van hanh » van thanh, ban hanh, van anh
hanh ca » hanh cac, hanh cat, hanh cua
nam xua » nam cua, nam mua, nam qua
so sanh » do sanh
nang xa » nang x, lang xa, nang ma
te sach » toc sach
nam xuc » cam xuc, nam thuc, nam duoc
ca cua » co cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((so sanh) or (te sach)) ky nang xa hoi. hieu van ((nam xuc) OR (nam xua)) van hanh ca cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sanh) OR (te sach)) ky nang xa hoi. hieu van ((nam xuc) OR (nam xua)) van hanh ca cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sanh) or (te sach)) ky nang xa hoi. hieu van ((nam xuc) OR (nam xua)) van hanh ca cua triet".
• Adding a wildcard symbol may retrieve word variants: ((so sanh) or (te sach)) ky nang xa hoi. hieu van ((nam xuc) OR (nam xua)) van hanh ca cua triet*.
