Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien danh
thien anh » thien danh, tien anh, thien thanh
thanh tra » thanh toan, thanh hoa
tuan dung » tuan duong, tran dung, tan dung
dung cong » dung trong
tra tuan » tran tuan, tra quan, tri tuan
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tai
toan tap » toan 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 ((thieu xanh) OR (thien anh)) - thanh tra tuan dung cong tan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (thien anh)) - thanh tra tuan dung cong tan ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (thien anh)) - thanh tra tuan dung cong tan ((toan cau) OR (toan tap))*.
