Perhaps you should try some spelling variations:
tieu xanh » tieu danh, chieu xanh, dieu hanh
tranh cua » doanh cua, manh cua
dung cong » dung trong
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, cong tan, huong dan
phan cau » phan cac, phan tu, toan cau
phan dau » phan tu, hang dau

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 - canh tranh cua dung cong dan ((((phan cau) OR (phan lap))) OR (phan dau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - canh tranh cua dung cong dan ((((phan cau) OR (phan lap))) or (phan dau))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - canh tranh cua dung cong dan ((((phan cau) OR (phan lap))) or (phan dau))*.
