Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
thanh tung » thanh cong
dung cong » dung trong
cong dan » cong san, cong tan, huong dan
tung ap » tang ap, tung dan, tung bay
ap dung » xay dung, van dung
dan van » dang van, doan van, dao van

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((chieu sach) OR (chiet tach)) - thanh tung ap dung cong dan van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sach) OR (chiet tach)) - thanh tung ap dung cong dan van ban*".
