Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
dong cong » duong cong, dung cong, dang cong
anh dang » anh dung, anh bang, anh danh
anh dong » anh huong, anh son
cua dong » chua dong, cua cong, cua dang
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
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: theo ((chuc nang) OR (chieu xanh)) - ((anh dang) OR (anh dong)) cua dong cong dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chuc nang) or (chieu xanh)) - ((anh dang) OR (anh dong)) cua dong cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chuc nang) or (chieu xanh)) - ((anh dang) OR (anh dong)) cua dong cong dan toan cao*.
