Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
canh doanh » hanh doanh, chinh doanh, doanh doanh
cua phuong » cuu phuong, cuc phuong, luan phuong
hien xanh » hien hanh, hien nhanh, hien khanh
cua khong » hua khong, cua thuong, cua cong
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan ban » van ban

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: hoc ((hien xanh) OR (chieu xanh)) - canh doanh ((cua khong) OR (cua phuong)) cong van toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (chieu xanh)) - canh doanh ((cua khong) or (cua phuong)) cong van toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (chieu xanh)) - canh doanh ((cua khong) or (cua phuong)) cong van toan ban*.
