Perhaps you should try some spelling variations:
chieu sang » chieu sach, hieu lang, nhieu tang
chieu xanh » chieu sach, chieu tinh, hieu manh
hanh trung » thanh trung, hanh trang, manh trung
trung cua » truong cua, trung tuan, trung cap
cua bang » chua bang, cua ban, cua dang
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
phan cau » phan dau, phan cac, phan tu

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 sang) OR (chieu xanh)) - hanh trung cua bang ((cong tan) OR (cong san)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu xanh)) - hanh trung cua bang ((cong tan) OR (cong san)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (chieu xanh)) - hanh trung cua bang ((cong tan) OR (cong san)) phan cau*.
