今年是台湾文献初祖沈光文诞辰400周年。为缅怀这位乡贤,本文依据有关资料,阐述沈光文于清初流寓台湾的艰苦经历,传播中华文化的业绩,及其牵系两岸文化情结的不朽功勋。同时介绍乾嘉以来的海峡两岸对沈光文的研究以及两岸文化交流和感情沟通,从而揭示大陆与台湾骨肉相亲的历史渊源。 This year marks the 400th anniversary of the birth of Taiwan’s ancestor Shen Guangwen. In memory of this Xiangxian, based on relevant information, this article expounds Shen Guangwen’s painstaking experience of shedding Taiwan in the early Qing Dynasty, disseminating the achievements of Chinese culture and his immortal feudal influence on the cross-Strait cultural complex. At the same time, he introduced the research on Shen Guangwen since the Qianghsia and the cross-Strait cultural exchange and emotional communication so as to reveal the historical origins of the fidelity between the mainland and Taiwan.
