Agree to disagree or "agreeing to disagree" describes or refers to a situation where two or more people or groups of people resolve conflict by reaching an agreement whereby both sides tolerate but do not accept the views,opinions or position of the other side.Both sides typically "agree to disagree" where they recognise that further conflict is unnecessary,ineffective or otherwise undesirable.They may also remain on amicable terms while continuing to disagree.
簡單來說就是同意各自保留不同意見(不再說服對方),或者用周總理的話來說：求同存異.
