Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trung tuan » trung thanh, trung tam, tran tuan
doi chieu » doc hieu, doi chi, ho chieu
cong cong » cong dong, trong cong, dung cong
dung cua » dung luan, dung cho
tan than » tan thanh, tan tran, tam than
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: doi chieu xanh - thanh ((dung cua) OR (trung tuan)) cong cong ((tan than) OR (ban than)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - thanh ((dung cua) or (trung tuan)) cong cong ((tan than) OR (ban than)) ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - thanh ((dung cua) or (trung tuan)) cong cong ((tan than) OR (ban than)) ban*.
