Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
hien xanh » hien hanh, hien nhanh, chieu xanh
luat dang » luat dan, luat doanh, luat quang
luat danh » luat doanh, luat dan, luat canh
cong dan » cong san, cong tan, huong dan
than tap » toan tap, han tap, phan tap
toan ban » van ban

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc hien xanh - hanh trinh ((luat dang) OR (luat danh)) cong dan ((than tap) or (toan ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - hanh trinh ((luat dang) OR (luat danh)) cong dan ((than tap) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - hanh trinh ((luat dang) OR (luat danh)) cong dan ((than tap) or (toan ban))*".
