Perhaps you should try some spelling variations:
phuong cong » phuong dong, phong cong, phung cong
thu phuong » thi phuong, thu huong, theo phuong
lieu tinh » trieu tinh, diep tinh, bien tinh
thanh tra » thanh toan, thanh hoa
van thanh » ban thanh, van tuan
dan chan » dan gian, dan ca, van chat
ho lieu » so lieu, co lieu, ho kieu
tra thu » tran thu, tra thuc, ta thu

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 lieu tinh - thanh tra thu phuong cong ((van thanh) OR (dan chan)) cau~.
• Adding a wildcard symbol may retrieve word variants: ho lieu tinh - thanh tra thu phuong cong ((van thanh) or (dan chan)) cau*.
