Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
cua dang » cua cong, cua ban
cong tap » cuong tap, cong tac, tong tap
cong tan » cong tac, cong san, cong thanh
toan ban » van 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 - thanh trung ((cua dang) OR (su dung)) ((cong tap) OR (cong tan)) toan ban~.
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - thanh trung ((cua dang) or (su dung)) ((cong tap) or (cong tan)) toan ban*.
