Perhaps you should try some spelling variations:
hanh trung » thanh trung, hanh trang, manh trung
chieu sach » chinh sach, chiet tach, chieu sang
thong cong » trong cong, tong cong, thong thong
chuc danh » chuc nganh, thuc hanh, chuc nang
trung cua » truong cua, trung tuan, trung cap
cua thong » cua thuong, cua khong, cua tong
dan toan » dan than, manh toan, xuan toan
van toan » van tuan, van tan, van thanh

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: cho ((chuc danh) OR (chieu sach)) - hanh trung cua thong cong ((dan toan) OR (van toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chuc danh) or (chieu sach)) - hanh trung cua thong cong ((dan toan) OR (van toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: cho ((chuc danh) or (chieu sach)) - hanh trung cua thong cong ((dan toan) OR (van toan)) cao*.
