Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien danh
thien anh » thien danh, tien anh, thien thanh
vat dung » va dung, viet dung, mat duong
van dung » van dong, xay dung, tin dung
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 ((thieu xanh) or (thien anh)) - hanh chinh ((vat dung) OR (van dung)) cong san than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (thien anh)) - hanh chinh ((vat dung) OR (van dung)) cong san than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (thien anh)) - hanh chinh ((vat dung) OR (van dung)) cong san than cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (thien anh)) - hanh chinh ((vat dung) OR (van dung)) cong san than cau*.
