Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh tung » thanh cong
hang cong » hang nong, bang cong, thanh cong
dang cong » dung cong
ho chieu » theo chieu, hoc thieu, doi chieu
san than » sang than, san thanh, ban than
than cap » khan cap, thanh lap, thanh cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - ((thanh trung) or (thanh tung)) va ((hang cong) OR (dang cong)) san than cap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((thanh trung) OR (thanh tung)) va ((hang cong) OR (dang cong)) san than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh trung) or (thanh tung)) va ((hang cong) OR (dang cong)) san than cap*".
