Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh dung » thanh dung, anh dung, hanh dong
luan nang » luan van, van nang, luan san
nang cong » nang song, dang cong, bang 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: theo ((chieu xanh) or (chieu tinh)) - hanh dung luan nang cong ((dan than) OR (van than)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu tinh)) - hanh dung luan nang cong ((dan than) OR (van than)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu tinh)) - hanh dung luan nang cong ((dan than) OR (van than)) cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu tinh)) - hanh dung luan nang cong ((dan than) OR (van than)) cau*.
