“西安事变”震惊中外,影响了中国革命的进程,促使了国内主战力量的联合,迫使蒋介石内外政策转变。从历史的宏观视角着眼,这场事变是历史偶然性和必然性的结合,恰如张学良、杨虎城在这场政治角逐下的遭遇,既有二人性格的使然也有现实的不可抗拒因素。 The “Xi’an Incident” shocked both China and foreign countries, affecting the process of the Chinese revolution, prompting a coalition of major domestic forces and forcing Chiang Kai-shek’s domestic and foreign policy changes. From a historical macro point of view, this incident is a combination of historical contingency and necessity, just as Zhang Xueliang and Yang Hucheng suffered during this political rivalry, both natural and actual irresistible factors.
