Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
dong doanh » dung doanh, trong doanh, doanh doanh
doi chieu » doc hieu, doi chi, ho chieu
doanh cua » doanh luan
cong doan » cong dan, cong hoan, cong san
phan cac » nhan cach, phan dau, phan lap
ban cua » ban quan

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 sang - canh ((doanh cua) OR (ban cua)) nhung ((cong doan) OR (dong doanh)) phan cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - canh ((doanh cua) or (ban cua)) nhung ((cong doan) OR (dong doanh)) phan cac~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - canh ((doanh cua) or (ban cua)) nhung ((cong doan) OR (dong doanh)) phan cac*.
