Perhaps you should try some spelling variations:
hanh doanh » hang doanh, chinh doanh, doanh doanh
doanh cua » doanh luan
song danh » song hanh, cong danh, dong danh
song xanh » song hanh, hoang xanh, duong xanh
ho chieu » theo chieu, hoc thieu, doi chieu
cua dang » cua cong, cua ban
toan tap » toan 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: ((hoc hien) OR (ho chieu)) xanh - hanh doanh cua dang ((song danh) OR (song xanh)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hien) or (ho chieu)) xanh - hanh doanh cua dang ((song danh) OR (song xanh)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc hien) or (ho chieu)) xanh - hanh doanh cua dang ((song danh) OR (song xanh)) toan tap*.
