Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tranh » hanh trinh, hanh trang, lanh tranh
dung chung » dung cong, dung ung, dung trung
ho chieu » theo chieu, hoc thieu, doi chieu
cua dung » cua dang, cua dong, qua dung
ban than » ban thanh, van thanh, ban hang
van than » van thanh, van thang, van tuan

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: ho chieu xanh - ((hanh tranh) OR (canh tranh)) cua dung chung ((ban than) OR (van than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh tranh) OR (canh tranh)) cua dung chung ((ban than) or (van than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh tranh) OR (canh tranh)) cua dung chung ((ban than) or (van than)) cau*.
