孙中山是中国民主革命的先行者,他不仅领导了推翻专制、建立共和的辛亥革命,而且在辛亥革命以后还多次发动了旨在维护辛亥革命果实的革命斗争。1919年北京爆发五四运动,孙中山马上作出反应,对运动给予极大声援和支持,具体表现有:(1)发挥上海《民国日报》舆论宣传的导向作用;(2)竭力营救被捕的爱国师生和工人;(3)推动和指导五四运动在上海的展开;(4)支持学生的爱国斗争,对五四运动给予肯定和赞许。孙中山对五四运动的声援与支持,一方面有力地推动了运动的发展与成功;另一方面,他本人的思想也发生了很大的变化。他从五四运动中看到了民众力量的伟大,开始酝酿改组国民党的工作。 Sun Yat-sen was the forerunner of the Chinese democratic revolution. He not only led the 1911 Revolution that overthrew autocracy and established a republic, but also repeatedly launched the revolutionary struggle aimed at safeguarding the fruits of the Revolution of 1911 after the Revolution of 1911. In 1919, when the May Fourth Movement broke out in Beijing, Sun Yat-sen responded immediately and gave great support and solidarity to the movement. The specific performance was as follows: (1) giving play to the role of public opinion in the Shanghai Republican Daily; (2) trying to rescue the arrested patriots Teachers and students and workers; (3) to promote and guide the May Fourth Movement in Shanghai; and (4) to support students’ patriotic struggle and affirm and applaud the May 4th Movement. Sun Yat-sen’s solidarity and support for the May 4th Movement have, on the one hand, effectively promoted the development and success of the movement; on the other hand, his own thinking has also undergone great changes. He saw the great power of the people from the May Fourth Movement and began to deliberate and reorganize the work of the Kuomintang.
