Perhaps you should try some spelling variations:

thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
cua nhung » va nhung
cong doan » cong dan, cong hoan, dong doanh
doan phan » doanh phan, toan phan, dan phan
tung cua » trung cua, tuong cua, dung cua
phan cau » phan dau, phan cac, phan tu

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 ((((chiet tach) OR (chieu sach))) OR (chinh sach)) - thanh tung cua nhung cong doan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chiet tach) OR (chieu sach))) or (chinh sach)) - thanh tung cua nhung cong doan phan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chiet tach) OR (chieu sach))) or (chinh sach)) - thanh tung cua nhung cong doan phan cau*.
