Perhaps you should try some spelling variations:
nhung chong » nhung cong, nhung phong, nhung phuong
nhieu tang » chieu sang, nhiet nang
hieu lang » chieu sang, hieu quang, hieu van
chinh cua » chinh ca, chinh sua, hinh cua
cua nhung » va nhung
dan than » dan chan, ban than, dan toan
van than » van thanh, van thang, van tuan

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: ho ((hieu lang) OR (nhieu tang)) - hanh chinh cua nhung chong ((dan than) OR (van than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu lang) or (nhieu tang)) - hanh chinh cua nhung chong ((dan than) OR (van than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) or (nhieu tang)) - hanh chinh cua nhung chong ((dan than) OR (van than)) cau*.
