Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu xanh
chieu sang » chieu xanh, hieu lang, nhieu tang
cua thuong » cua truong, ca thuong, cua huong
cua phuong » cuu phuong, cuc phuong, luan phuong
hanh mang » nhanh mang, hanh trang, nhanh lang
cong dan » cong san, cong tan, huong dan
dan khan » dan khanh, dan chan, dan than
khan ap » khan cap, han ap, khan dam

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 ((chieu sach) OR (chieu sang)) - hanh mang ((cua thuong) OR (cua phuong)) cong dan khan ap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) or (chieu sang)) - hanh mang ((cua thuong) OR (cua phuong)) cong dan khan ap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) or (chieu sang)) - hanh mang ((cua thuong) OR (cua phuong)) cong dan khan ap*.
