Perhaps you should try some spelling variations:
hieu nganh » vien nganh, hiem ngan, hieu manh
hanh trung » thanh trung, hanh trang, manh trung
cong danh » cuong danh, cong dan, cong thanh
danh toan » manh toan, anh toan, dan toan
kha nang » phap nang, ky nang, thi nang
toan cau » toan cao, toan ban, toan tap
ki nang » ky nang

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((hieu nganh) or (dieu hanh)) - hanh trung ((kha nang) OR (ki nang)) cong danh toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hieu nganh) OR (dieu hanh)) - hanh trung ((kha nang) OR (ki nang)) cong danh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu nganh) or (dieu hanh)) - hanh trung ((kha nang) OR (ki nang)) cong danh toan cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu nganh) or (dieu hanh)) - hanh trung ((kha nang) OR (ki nang)) cong danh toan cau*.
