Chen Duxiu met Cai Yuanpei in Shanghai, who was about to go abroad for training. He admired Cai Yuanpei's inclusive educational philosophy. Wang Daxie and Wu Zhihui also bid farewell to him. However, Chen Duxiu and Wu Zhihui had great conflicting views and did not hesitate to express their opinions. Warning him not to continue to play Yannian Qiaonian's realism, Cai Yuanpei reminded him that although his views were different, he could still make plans, and he needed to discuss the development direction of the May Fourth Movement with Hu Shizhi and Li Dazhao more often.

Li Dazhao and Hu Shizhi set off for Shanghai. Chen Duxiu happily carried two jars of Erguotou and went with them to the mountains to sit in the grass and have a picnic. Hu Shizhi was very dissatisfied with the current situation that "New Youth" had become a democratic journal. Since Chen Duxiu had to go to Guangzhou to take a job, his colleagues in the content editorial department wanted to move "New Youth" to Beijing, but how should they deal with everyone after moving to Beijing? It also has different tastes.

Mr. Lu Xun suggested that Chen Duxiu should pursue him, so Chen Duxiu clearly proposed that "New Youth" would be left in Shanghai to be organized and compiled by Chen Wangdao again. Hu Shizhi did not object, but he could not persuade or stop his friend. , all that is left is regret and sadness.

Chen Duxiu opened the skylight and spoke frankly. The lofty ideal and pursuit of him and Li Dazhao was to save our country on the road of Marxism-Leninism. However, Hu Shizhi believed that France, the birthplace of communist society, had not achieved communism. Wealthy, Russia has only been a communist society for two years, how can they judge that a communist society is feasible in our country

Chen Duxiu and Li Dazhao believed in his choice and believed that it was the will of China and the people. Although Hu Shizhi held different views, he also felt that the friendship between the three people was deep and valuable. Chen Duxiu said that the three brothers should always treat each other with sincerity and leave their beliefs and choices to history and future generations for comment.
