Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
lieu tinh » trieu tinh, diep tinh, bien tinh
hanh dung » thanh dung, anh dung, hanh dong
cua nhung » va nhung
dung cua » dung luan, dung cho
dan than » dan chan, van than, dan toan
ban than » ban thanh, van thanh, ban hang

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: theo ((chieu xanh) OR (lieu tinh)) - hanh dung cua nhung cong ((dan than) OR (ban than)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (lieu tinh)) - hanh dung cua nhung cong ((dan than) OR (ban than)) tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (lieu tinh)) - hanh dung cua nhung cong ((dan than) OR (ban than)) tap*.
