《中国近代现代史》下册第一章第一节在讲述“东北易帜”影响时写到:“这样,国民政府形式上统一了‘全国”’。为什么要加上“形式上”三字?理由有四: 一、国民党内部派系斗争十分激烈。有蒋派、汪派、桂系等等。二、东北易帜后,国民党各派新军阀盘踞一方,混战不断,先后有蒋桂战争、蒋冯战争、中原大战等 In the first section of the first chapter of the book “Modern History of Modern China,” when describing the influence of the “Northeast Renewal,” he wrote: “In this way, the National Government formally unified the ’nation’.” Why do we have to add the word “formally”? There are four reasons: First, the Kuomintang’s internal factional struggle is very fierce. There are Jiang, Wang, Gui, and so on. 2. After the Northeast was re-branded, the new warlords of the Kuomintang each entrenched in one side and continued the melee. There have been the Jiang Gui War, Jiang Feng War, and the Central Plains War.
