Perhaps you should try some spelling variations:
trieu minh » trieu tinh, trien minh, trien kinh
trien dich » mien dich
nhung cong » dung cong, thong cong, hang cong
dung cua » dung luan
cong san » cong tac
san than » sang than, san thanh, ban than
than cau » toan cau, phan cau, than cap

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((trieu minh) or (trien dich)) - hanh ((dung cua) OR (dung cho)) nhung cong san than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((trieu minh) OR (trien dich)) - hanh ((dung cua) OR (dung cho)) nhung cong san than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((trieu minh) or (trien dich)) - hanh ((dung cua) OR (dung cho)) nhung cong san than cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((trieu minh) or (trien dich)) - hanh ((dung cua) OR (dung cho)) nhung cong san than cau*.
