Perhaps you should try some spelling variations:
hanh trung » thanh trung, hanh trang, manh trung
chieu sach » chinh sach, chiet tach, chieu sang
chuc danh » chuc nganh, thuc hanh, chuc nang
trung cua » truong cua, trung tuan, trung cap
cua thong » cua thuong, cua khong, cua tong
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
toan cao » toan ban, toan tap

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) OR (cong san)) 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) OR (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: cho ((chuc danh) or (chieu sach)) - hanh trung cua thong ((cong dan) OR (cong san)) toan cao*.
