Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
truong cua » truong ca, truong quan, huong cua
truong cao » truong dai
doi chieu » doc hieu, doi chi, ho chieu
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
chan cau » phan cau, can cau, chinh cau

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: doi chieu xanh - thanh ((truong cua) OR (truong cao)) dung ((cong dan) OR (cong san)) chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - thanh ((truong cua) or (truong cao)) dung ((cong dan) OR (cong san)) chan cau~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - thanh ((truong cua) or (truong cao)) dung ((cong dan) OR (cong san)) chan cau*.
