Is it because of Song Meiling that Zhang Xueliang survived after the Xi Incident?

Song Meiling said that Zhang Xueliang's behavior destroyed the foundation of national unity: order and rules. She continued to implore Zhang Xueliang to do everything possible to ensure her husband's release. He replied that he must consult with his colleagues before taking action. Song waited patiently. Seeing that it was midnight, she called Zhong and asked if she had made a decision. He explained that he had no new news. He was willing to let the leader go, but his colleagues were unwilling, accusing him of letting himself suffer passively in the negotiations.

Gradually, I feel that I have successfully split the two camps of Zhang and Yang. According to Song, Zhang Xueliang hinted that he was willing to take action against the wishes of his ally Yang Hucheng. Song Meiling claimed that he planned to send her away under the pretext of continuing negotiations with senior officials in Nanjing, and secretly sent the generalissimo out of Xi 'an in disguise, to a place close to the government forces, and then to Luoyang. Song said that she flatly rejected the proposal, fearing that long-distance fatigue by car would harm her husband's health under the circumstances mentioned in the proposal. More importantly, she believes that this is not the proper way for leaders to reach the capital. From her point of view, Zhang Xueliang had no choice but to persuade his colleagues to release the leader respectfully.
