Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh hung, hanh dung
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
doi chinh » do chinh, tai chinh, hoc chinh
cua nhung » va nhung
toan cao » toan ban
toan tap » toan 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: doi chinh sach - ((thanh dung) OR (thanh tung)) cua nhung cong trinh ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chinh sach - ((thanh dung) OR (thanh tung)) cua nhung cong trinh ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: doi chinh sach - ((thanh dung) OR (thanh tung)) cua nhung cong trinh ((toan cao) or (toan tap))*.
