Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
hien xanh » hien hanh, hien nhanh, hien khanh
tranh cua » doanh cua, manh cua
hang nong » thang long, han tong
dan can » dan chan, dan canh, dan ca
can cau » van cau, ban cau, ca cau

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 tranh cua ((nhung cong) OR (hang nong)) dan can cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (chieu xanh)) - canh tranh cua ((nhung cong) or (hang nong)) dan can cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (chieu xanh)) - canh tranh cua ((nhung cong) or (hang nong)) dan can cau*.
