Perhaps you should try some spelling variations:
chinh sua » chinh su, chinh cua, chinh luan
dung cong » dung trong
ho trieu » mot trieu, 30 trieu, ho chieu
25 trieu » 30 trieu
chinh ca » chinh ta, chinh va, chinh tai
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

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: ((ho trieu) OR (25 trieu)) tinh - hanh ((chinh sua) OR (chinh ca)) dung cong dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (25 trieu)) tinh - hanh ((chinh sua) or (chinh ca)) dung cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (25 trieu)) tinh - hanh ((chinh sua) or (chinh ca)) dung cong dan toan cao*.
