Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh hung » thanh huong, thanh tung, thanh cong
tong cong » cong cong, dung cong, dang cong
danh toan » manh toan, anh toan, dan toan
ho chieu » theo chieu, hoc thieu, doi chieu
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: ho chieu xanh - ((thanh hung) OR (thanh trung)) cua ((tong cong) OR (trong cong)) danh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((thanh hung) OR (thanh trung)) cua ((tong cong) or (trong cong)) danh toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((thanh hung) OR (thanh trung)) cua ((tong cong) or (trong cong)) danh toan cao*.
