Perhaps you should try some spelling variations:
phuong cong » phuong dong, phong cong, phung cong
chieu sach » chiet tach, chieu sang, chieu xanh
thanh tung » thanh cong
va phuong » va thuong, cac phuong
cong dan » cong san, cong tan, huong dan
toan cao » toan ban, toan tap
chan cho » chat cho, han cho, chuan chon
tung va » trung va, tuong va, dung va

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 ((chieu sach) OR (chinh sach)) - thanh tung va phuong cong dan ((toan cao) OR (chan cho))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chinh sach)) - thanh tung va phuong cong dan ((toan cao) or (chan cho))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chinh sach)) - thanh tung va phuong cong dan ((toan cao) or (chan cho))*.
