Perhaps you should try some spelling variations:
thanh tung » thanh cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
tung cho » dung cho, tung ho, tang cho
cho dung » cho dong, cho ung, cao dung
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
than cau » toan cau, than cap, thanh chau
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: theo tieu xanh - thanh tung cho dung ((cong dan) OR (cong san)) ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - thanh tung cho dung ((cong dan) OR (cong san)) ((than cau) or (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - thanh tung cho dung ((cong dan) OR (cong san)) ((than cau) or (phan cau))*.
