Perhaps you should try some spelling variations:
cang thang » cong thanh, dang thanh
chieu xanh » chieu sach, chieu sang, chieu tinh
hang hang » nang hang, hung thang, lang thang
dang cong » dung cong
ho chieu » theo chieu, hoc thieu, doi chieu
cua dang » cua cong, cua ban
dan toan » van toan, dan than, manh 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 chieu xanh - ((hang hang) OR (cang thang)) cua dang cong ((dan toan) OR (van than)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hang hang) OR (cang thang)) cua dang cong ((dan toan) or (van than)) cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hang hang) OR (cang thang)) cua dang cong ((dan toan) or (van than)) cao*.
