Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tran » thanh trang, thanh toan, thanh tuan
hoc chieu » hoc thieu, ho chieu, hoc hien
thanh tra » thanh toan, thanh hoa
cong lang » cong vang, cong luong, cong quang
cong san » cong tac
tan cau » toan cau, van cau, tan ca

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 - ((thanh tran) OR (thanh tra)) va thuong ((cong san) OR (cong lang)) tan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - ((thanh tran) OR (thanh tra)) va thuong ((cong san) or (cong lang)) tan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((thanh tran) OR (thanh tra)) va thuong ((cong san) or (cong lang)) tan cau*.
