Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
va thong » va thuong, va phuong, he thong
cong dan » cong san, cong tan, huong dan
cong tac » cong ty
toan cao » toan ban, toan tap
cong va » dong va, cong ha, luong va

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: toc ((thieu xanh) OR (chieu xanh)) - thanh cong va thong ((cong dan) OR (cong tac)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu xanh) OR (chieu xanh)) - thanh cong va thong ((cong dan) or (cong tac)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu xanh) OR (chieu xanh)) - thanh cong va thong ((cong dan) or (cong tac)) toan cao*.
