Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
manh trung » manh tung, thanh trung, sinh trung
hoc chieu » hoc thieu, ho chieu, hoc hien
manh hung » anh huong
dang cong » dung cong
cua dang » cua cong, cua ban
toan cao » toan tap
toan ban » van ban

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 chieu xanh - ((manh trung) OR (manh hung)) cua dang cong trinh ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - ((manh trung) or (manh hung)) cua dang cong trinh ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((manh trung) or (manh hung)) cua dang cong trinh ((toan cao) OR (toan ban))*.
