Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tung » thanh cong
doi chieu » doc hieu, doi chi, ho chieu
cong doan » cong hoan, dong doanh, cong san
ca thong » ca thuong, va thong, ca trong
cong dan » cong san, cong tan, huong dan
tung ca » trung ca, tang ca, cung ca

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - thanh tung ca thong ((cong doan) OR (cong dan)) phan tu~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - thanh tung ca thong ((cong doan) OR (cong dan)) phan tu*.
