对于国民党1949年在大陆政权垮台的原因,有多种说法。有的认为是蒋介石指挥不当造成的,有的认为是共产党打入国民党内部的特工人员窃取机密作战情报使国民党军队作战陷于被动造成的,有的认为是一些国民党部队起义造成的,等等。 There are various reasons why the KMT regime collapsed in the mainland in 1949. Some think it was caused by Chiang Kai-shek’s improper command. Some think that secret agents who penetrated inside the Kuomintang by members of the Communist Party secretly steal confidential operational information and cause the Kuomintang troops to be forced into passive operations. Some believe it is caused by some Kuomintang troops’ uprisings.
