Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
cong cua » cong cu, dong cua, huong cua
ban quan » van quan
dan toan » van toan, manh toan, xuan toan
dan than » dan chan, ban than, van than

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 - hanh ((cong cua) OR (ban quan)) nhung cong ((dan toan) OR (dan than)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh ((cong cua) or (ban quan)) nhung cong ((dan toan) or (dan than)) cau*.
