Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, truong thanh
hanh tranh » canh tranh, hanh trinh, hanh trang
chuc danh » chuc nganh, thuc hanh, chuc nang
tranh cua » doanh cua, manh cua
chu manh » ho manh, chu han, chu van
cua bang » chua bang, cua ban, cua dang
cong tan » cong tac, cong san, cong ty
chan cau » phan cau, can cau, chinh cau

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 (chu manh)) - hanh tranh cua bang ((cong tan) OR (cong thanh)) chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chuc danh) or (chu manh)) - hanh tranh cua bang ((cong tan) OR (cong thanh)) chan cau~".
• Adding a wildcard symbol may retrieve word variants: cho ((chuc danh) or (chu manh)) - hanh tranh cua bang ((cong tan) OR (cong thanh)) chan cau*.
