Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, nhung don
chieu sach » chinh sach, chiet tach, chieu sang
hang cong » dang cong, hang nong, bang cong
anh dang » anh dong, anh dung, anh bang
dang vat » dang van, dong vat, dang nhat
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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 ((ho manh) OR (chieu sach)) - anh dang vat ((nhung cong) OR (hang cong)) dan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((ho manh) or (chieu sach)) - anh dang vat ((nhung cong) OR (hang cong)) dan than cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((ho manh) or (chieu sach)) - anh dang vat ((nhung cong) OR (hang cong)) dan than cao*.
