孙中山在世时，林森不但没有明显的反共言行，而且为改组国民党，促进国共合作做了有益工作。后来，他由于“一时受惑”，并在被排挤的状况下，参加了旨在排共、兼有防苏、惩汪之意的西山会议，但对西山会议派在上海另立中央的分裂活动，林森则基本上不参与、不支持、不评论，持超然的态度。因此，林森虽然名义上曾是西山会议的领衔召集者，实际上不是其核心人物，而且是较早从中脱身。任其衰落的旁观者。 When Sun Yat-sen was alive, Lin Sen not only did not have obvious anti-communist talk but also did useful work for the reorganization of the Kuomintang and the promotion of the KMT-CPC cooperation. Later, due to being “confused for a moment,” he was participating in the Xishan Conference aimed at eliminating the Soviet Union and punishing Wang for the purpose of co-operation and elimination. However, due to the split activities of the Xishan conference dispatched in a separate central government in Shanghai, Lin Sen is basically not involved, do not support, do not comment, hold a detached attitude. As a result, Linsen, although nominally a convener of the Xishan conference, is actually not a core figure and is extricated from it earlier. Let the decline of bystanders.
