Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chiet tach » chieu sach
canh doanh » hanh doanh, chinh doanh, doanh doanh
cua thong » cua thuong, cua khong, suat thong
cua tong » cua cong, cua dong, cua nong
cong san » cong tac
san phan » san pham, van phan, sat phan

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) OR (chiet tach)) - canh doanh ((cua thong) OR (cua tong)) cong san phan tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chiet tach)) - canh doanh ((cua thong) OR (cua tong)) cong san phan tu~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chiet tach)) - canh doanh ((cua thong) OR (cua tong)) cong san phan tu*.
