Perhaps you should try some spelling variations:
nhieu tang » chieu sang, hieu lang, nhiet nang
thien van » thi van
dang nong » dang cong, hang nong, tang nong
chinh su » hinh su, chinh phu, chinh ta
dan than » dan chan, ban than, dan toan
van than » van thanh, van thang, van tuan
su dang » su dung

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((thien van) or (nhieu tang)) - hanh chinh su dang nong ((dan than) OR (van than)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((thien van) OR (nhieu tang)) - hanh chinh su dang nong ((dan than) OR (van than)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((thien van) or (nhieu tang)) - hanh chinh su dang nong ((dan than) OR (van than)) cau".
• Adding a wildcard symbol may retrieve word variants: ho ((thien van) or (nhieu tang)) - hanh chinh su dang nong ((dan than) OR (van than)) cau*.
