Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu sang » chieu sach, chieu xanh, hieu lang
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh cua » doanh cua, manh cua
cua nhung » va nhung
cong manh » duong manh, cong thanh, hoang manh
cong danh » cuong danh, cong dan, cong thanh

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 sang - hanh tranh cua nhung ((cong manh) OR (cong danh)) van ban~.
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - hanh tranh cua nhung ((cong manh) or (cong danh)) van ban*.
