Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
doanh luan » doanh nhan
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, ho chieu
tranh cua » doanh cua, manh cua
cong dan » cong san, cong tan, huong dan
thai cao » thoai cac, thuat cao, toan cao
tai cao » tao cao, tai sao, tai cac

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 - hanh ((tranh cua) OR (doanh luan)) nhung cong dan ((thai cao) OR (tai cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - hanh ((tranh cua) or (doanh luan)) nhung cong dan ((thai cao) OR (tai cao))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - hanh ((tranh cua) or (doanh luan)) nhung cong dan ((thai cao) OR (tai cao))*.
