Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
triet tinh » trieu tinh, trien tinh, trien kinh
canh doanh » hanh doanh, doanh doanh, kinh doanh
mon triet » minh triet, bo triet, mao triet
luan han » luan hoan, luan phan, luan van
cong dan » cong san, cong tan, cong dong
toan cau » toan cao, toan ban, toan tap

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

• If you are trying to use Boolean operators, they must be ALL CAPS: mon triet tinh - ((canh doanh) OR (chinh doanh)) luan han ((cong dan) OR (huong dan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "mon triet tinh - ((canh doanh) or (chinh doanh)) luan han ((cong dan) OR (huong dan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: mon triet tinh - ((canh doanh) or (chinh doanh)) luan han ((cong dan) OR (huong dan)) toan cau*.
