Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
thong cua » thong tu, huong cua
bang than » bang thanh, ban than, bang nhan
sang than » cang thang, dang thanh, sang tao
ho chieu » theo chieu, hoc thieu, doi chieu

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 - thanh ((thong cua) OR (thong quan)) nhung cong ((bang than) OR (sang than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh ((thong cua) OR (thong quan)) nhung cong ((bang than) or (sang than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((thong cua) OR (thong quan)) nhung cong ((bang than) or (sang than)) cau*.
