Perhaps you should try some spelling variations:
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh tang » hanh trang, anh tang, hanh mang
tang luan » dung luan
luan hang » luan nang, luan han, luan hung
hang cong » dang cong, hang nong, bang cong
dan chinh » dang chinh, van chinh, ban chinh
lan chinh » luan chinh, van chinh, hanh chinh

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 luan hang cong ((dan chinh) OR (lan chinh)) ca~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh tang luan hang cong ((dan chinh) OR (lan chinh)) ca*.
