Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
cuong cong » duong cong, dung cong, trong cong
luong cong » dung cong, trong cong, tong cong
thanh tra » thanh toan, thanh hoa
cong cong » cong dong, trong cong, dung cong
dan khoan » dan khoa, dai khoang, toan khoan
khoan cam » khoa cam, khoan va, phan cam
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: toc thieu xanh - thanh tra van ((((cuong cong) OR (luong cong))) OR (cong cong)) dan khoan cam~.
• Adding a wildcard symbol may retrieve word variants: toc thieu xanh - thanh tra van ((((cuong cong) or (luong cong))) or (cong cong)) dan khoan cam*.
