Perhaps you should try some spelling variations:
tien manh » tien anh, tien thanh, tran manh
canh manh » lanh manh, canh tranh, cach mang
cua nhung » va nhung
manh cua » doanh cua, ban cua
cong van » cong vang, cong san, cong tan
song van » hoang van, trong van, duong van
chat cau » chat cam, chat cao, chat va

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 ((tien manh) OR (tieng anh)) - canh manh cua nhung ((cong van) OR (song van)) chat cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((tien manh) OR (tieng anh)) - canh manh cua nhung ((cong van) or (song van)) chat cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((tien manh) OR (tieng anh)) - canh manh cua nhung ((cong van) or (song van)) chat cau*.
