Perhaps you should try some spelling variations:
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh tang » hanh trang, hanh mang, hanh tung
cua nhung » va nhung
anh tang » anh bang, anh dang, anh nang
cua hang » cua dang, cua cong, cua ban
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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 hang) OR (cua nhung)) cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh tang) OR (anh tang)) ((cua hang) OR (cua nhung)) cong dan than cao*.
