Perhaps you should try some spelling variations:

thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
doanh luan » doanh nhan
thong cong » trong cong, tong cong, thong thong
hang cong » dang cong, hang nong, bang cong
van toan » van tuan, van tan, van thanh
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 (chieu xanh)) - hoang doanh luan ((hang cong) OR (thong cong)) van toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - hoang doanh luan ((hang cong) or (thong cong)) van toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - hoang doanh luan ((hang cong) or (thong cong)) van toan cau*.
