Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh
thien danh » thien anh, thien dang, thien thanh
chieu xanh » chieu sach, chieu sang, chieu tinh
luan thong » luan phong, luan tuong, luat thong
thong cong » trong cong, tong cong, thong thong
hanh dung » thanh dung, anh dung, hanh dong
cong tinh » cong trinh, cong vinh, long tinh
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: hoc ((((thieu xanh) OR (thien danh))) OR (chieu xanh)) - hanh dung luan thong cong tinh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((thieu xanh) OR (thien danh))) or (chieu xanh)) - hanh dung luan thong cong tinh toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((thieu xanh) OR (thien danh))) or (chieu xanh)) - hanh dung luan thong cong tinh toan cau*.
