Perhaps you should try some spelling variations:
nhieu tang » chieu sang, nhiet nang
hieu lang » chieu sang, hieu quang, hieu van
ganh nang » anh nang, nganh nong, van nang
nang doc » nang luc
doc cong » hoc cong, duc cong, do cong
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.

• Performing a fuzzy search may retrieve terms with similar spellings: hoi ((hieu lang) or (nhieu tang)) - ganh nang doc cong dong ((dan than) OR (van than)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoi ((hieu lang) OR (nhieu tang)) - ganh nang doc cong dong ((dan than) OR (van than)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoi ((hieu lang) or (nhieu tang)) - ganh nang doc cong dong ((dan than) OR (van than)) cau".
• Adding a wildcard symbol may retrieve word variants: hoi ((hieu lang) or (nhieu tang)) - ganh nang doc cong dong ((dan than) OR (van than)) cau*.
