Perhaps you should try some spelling variations:
nhanh trinh » hanh trinh, nhanh tinh, thanh trinh
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
trinh ban » trinh han, trinh san, trinh dan
ban thanh » ban hanh, ban hang
dan than » dan chan, van than, dan toan
ban than » van thanh, ban hang, ban hanh

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: theo chieu xanh - nhanh trinh ban thanh cong ((dan than) OR (ban than)) ban~.
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - nhanh trinh ban thanh cong ((dan than) or (ban than)) ban*.
