Professor Chiang Yung-ching and Professsor Liu Wei-kai from Taiwan have both published articles with in-depth analysis of the process which saw Zhang move from co-operating with the Communists to launching the Xi'an Incident, and they put their case very clearly.
台北的蔣永敬教授、劉維開教授也著有專文發表，對張氏由聯共而發動兵變的過程，有極深入的分析，說得很清楚。
