Perhaps you should try some spelling variations:
thanh tuong » thanh thuong, thanh tung, thanh huong
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
tuong cua » truong cua, huong cua, thong cua
phan cong » thanh cong
tan toan » tan tran, tap toan, van toan
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: theo ((chieu xanh) OR (chieu sach)) - thanh tuong cua ((phan cong) OR (han tong)) tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - thanh tuong cua ((phan cong) or (han tong)) tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - thanh tuong cua ((phan cong) or (han tong)) tan toan tap*.
