Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
hanh tang » hanh trang, anh tang, hanh mang
chu xanh » chu manh, chieu xanh, chuc danh
tang cua » mang cua, hang cua, tang luan
cua dong » chua dong, cua cong, cua dang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong 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: theo ((chu xanh) OR (chua xang)) - hanh tang cua dong ((cong dan) OR (cong tan)) van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chua xang)) - hanh tang cua dong ((cong dan) OR (cong tan)) van ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chua xang)) - hanh tang cua dong ((cong dan) OR (cong tan)) van ban*.
