Perhaps you should try some spelling variations:
thanh tra » thanh toan, thanh hoa
dung cong » dung trong
dan khoan » dan khoa, dai khoang, toan khoan
khoan cam » khoa cam, khoan va, phan cam
van dung » van dong, xay dung, tin dung
cong dan » cong san, cong tan, huong dan
tra van » tran van, ta van, trang van

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) OR (hoc hien))) OR (toc thieu)) xanh - thanh tra van dung cong dan khoan cam~.
• Adding a wildcard symbol may retrieve word variants: ((((hoc thieu) or (hoc hien))) or (toc thieu)) xanh - thanh tra van dung cong dan khoan cam*.
