Perhaps you should try some spelling variations:
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh tang » hanh trang, hanh mang, hanh tung
cua thanh » gia thanh, va thanh, ha thanh
anh tang » anh bang, anh dang, anh nang
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

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: "theo tieu xanh - ((hanh tang) OR (anh tang)) cua thanh cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh tang) OR (anh tang)) cua thanh cong dan toan cau*.
