chieu xanh » chieu sach, chieu sang, chieu tinh
hien xanh » hien hanh, hien nhanh, hien khanh
cong tinh » cong vinh, long tinh, cong thanh
dai dung » dai duong, dan dung, mai dung
toan cau » toan cao, toan ban, toan tap

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((hien xanh) OR (chieu xanh)) - hanh truong dai dung ((cong tinh) or (cong trinh)) toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (chieu xanh)) - hanh truong dai dung ((cong tinh) OR (cong trinh)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (chieu xanh)) - hanh truong dai dung ((cong tinh) or (cong trinh)) toan cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (chieu xanh)) - hanh truong dai dung ((cong tinh) or (cong trinh)) toan cau*.
