Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
hieu manh » chieu xanh, hieu nganh, dieu hanh
anh mang » hanh mang, anh bang, anh dang
mang cua » manh cua, dung cua, ban cua
cua bang » chua bang, cua ban, cua dang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
gian cao » gian cac, gian co, giai cao

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 ((hieu manh) OR (chieu sang)) - anh mang cua bang ((cong dan) OR (cong tan)) gian cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu manh) or (chieu sang)) - anh mang cua bang ((cong dan) OR (cong tan)) gian cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu manh) or (chieu sang)) - anh mang cua bang ((cong dan) OR (cong tan)) gian cao*.
