Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
cong thanh » dong thanh, cong trinh, cong tan
hanh han » hanh nhan, hanh phan, hanh san
cua dang » cua cong, cua ban
cong dan » cong san, cong tan, huong dan
han cua » hang cua, nhan cua, than cua

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: ho ((chieu xanh) OR (chieu sang)) - hanh han cua dang ((cong dan) OR (cong thanh)) van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - hanh han cua dang ((cong dan) or (cong thanh)) van ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - hanh han cua dang ((cong dan) or (cong thanh)) van ban*.
