Perhaps you should try some spelling variations:
hoc nganh » hoc nhanh
cau triet » cau trieu, su triet, cua triet
hieu van » hieu va, thien van, lieu va
nganh ky » nganh y, nganh xay, hanh ky
van hanh » van thanh, ban hanh, van anh
nang xa » nang x, lang xa, nang ma
va danh » va dinh, va dan, va hanh
hac du » cac du, han du, hoc du
vi cau » va cau, ve cau, di cau
hac de » hoc de, tac de, hat de

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc nganh ky nang xa hoi. hieu van ((hac du) OR (hac de)) ((van hanh) or (va danh)) vi cau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc nganh ky nang xa hoi. hieu van ((hac du) OR (hac de)) ((van hanh) OR (va danh)) vi cau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc nganh ky nang xa hoi. hieu van ((hac du) OR (hac de)) ((van hanh) or (va danh)) vi cau triet".
• Adding a wildcard symbol may retrieve word variants: hoc nganh ky nang xa hoi. hieu van ((hac du) OR (hac de)) ((van hanh) or (va danh)) vi cau triet*.
