一在已经过去的岁月中发生的人和事,构成了所谓的历史,它如流水般地正在远去、消失。把历史中的某些部分拣出来加以回放评说,便是历史研究。之所以拾起并激活那部分历史,是当今时代的脉搏与它发生了共鸣;是时代的需要,需要借历史之事 The people and events that have taken place in the time that has passed constitute the so-called history, which is flowing and disappearing like a stream of water. It is a historical study to sort out some parts of history and comment on it. The reason why picking up and activating that part of history is that the pulse of the present age resonates with it. It is the need of the times and the need of borrowing history.
