Perhaps you should try some spelling variations:
nhieu tang » chieu sang, hieu lang, nhiet nang
hoc nhieu » hoc thieu, hoc nhiet, hop nhieu
nhung don » nhung van, nhung bo
hang cong » dang cong, hang nong, bang cong
van thanh » ban thanh, van tuan
chinh ca » chinh ta, chinh va, chinh tai
dan than » dan chan, ban than, van than

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: hoc nhieu tang - hanh chinh ca ((nhung don) OR (hang cong)) ((van thanh) OR (dan than)) cau~.
• Adding a wildcard symbol may retrieve word variants: hoc nhieu tang - hanh chinh ca ((nhung don) or (hang cong)) ((van thanh) or (dan than)) cau*.
