Perhaps you should try some spelling variations:
chieu tach » chieu sach, chiu trach, chieu tinh
chiet tach » chieu sach
tong cong » trong cong, cong cong, dung cong
cong cua » cong cu, dong cua, huong cua
cua tong » cua cong, cua dong, cua nong
cong dan » cong san, cong tan, huong dan
phan cau » phan cac, phan tu, phan lap
phan dau » phan tu, hang dau

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