Perhaps you should try some spelling variations:
nhanh lang » nhanh quang, nhanh thang, nhan dang
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh manh » hanh mang, lanh manh, hoang manh
dung cong » dung trong
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, cong tan, huong dan
toan cao » toan tap
toan ban » van ban

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 manh) OR (nhanh lang)) cua dung cong dan ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh manh) OR (nhanh lang)) cua dung cong dan ((toan cao) OR (toan ban))*.
