Perhaps you should try some spelling variations:
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh tang » hanh trang, anh tang, hanh tung
hanh mang » nhanh mang, hanh trang, nhanh lang
cong lang » cong vang, cong luong, cong quang
lang toan » dang toan, lang thang, lang thanh
cua dang » cua cong, cua ban
toan ban » van ban

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 - ((hanh tang) OR (hanh mang)) ((cua dang) OR (ung dung)) cong lang toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - ((hanh tang) OR (hanh mang)) ((cua dang) or (ung dung)) cong lang toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh tang) OR (hanh mang)) ((cua dang) or (ung dung)) cong lang toan ban*.
