Perhaps you should try some spelling variations:
thien chinh » tien thinh, thien chien, thi chinh
theo chinh » te chinh, che chinh, thi chinh
cua khong » hua khong, cua phuong, cua thuong
anh dung » anh dong, anh huong, sach dung
cua tong » cua cong, cua dong, cua nong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than tap » toan tap, han tap, phan 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: ((theo chinh) OR (thien chinh)) sach - anh dung ((cua khong) OR (cua tong)) cong dan than tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chinh) OR (thien chinh)) sach - anh dung ((cua khong) or (cua tong)) cong dan than tap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chinh) OR (thien chinh)) sach - anh dung ((cua khong) or (cua tong)) cong dan than tap*.
