Perhaps you should try some spelling variations:
chuc danh » chuc nganh, thuc hanh, chuc nang
chua xang » chua nang, chuc nang, chu bang
hanh tang » hanh trang, anh tang, hanh mang
van thong » van thuong, van phong, va thong
tang van » dang van, hoang van, trong van
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cau » 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: theo ((chuc danh) OR (chua xang)) - hanh tang van thong ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chuc danh) or (chua xang)) - hanh tang van thong ((cong dan) OR (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chua xang)) - hanh tang van thong ((cong dan) OR (cong tan)) toan cau*.
