Perhaps you should try some spelling variations:
phung cong » nhung cong, phong cong, nhung chong
hanh dung » thanh dung, anh dung, hanh dong
van phung » van phong, van hung, van chuong
theo chu » theo chieu, chao chu, theo yeu
dung van » duong van, dung va, dang van
dan toan » van toan, dan than, manh toan
cho chu » cho thue

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 chu) OR (cho chu)) sach - hanh dung van phung cong ((dan toan) OR (anh tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (cho chu)) sach - hanh dung van phung cong ((dan toan) or (anh tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (cho chu)) sach - hanh dung van phung cong ((dan toan) or (anh tuan)) cau*.
