From March 1947 onwards, due to the failure of the all-out offensive against the Liberated Areas in the previous eight months, Chiang Kai-shek had no choice but to change the all-out offensive to the key offensive against the Liberated Areas of Shandong and Northern Shaanxi. In particular, the intention of attacking the northern Shaanxi Border Region is obvious, in order to expel the CPC Central Committee and the PLA headquarters from the northwest, surround and annihilate the Northwest PLA near Yan'an, or force the PLA to cross the Yellow River in the east and then attack and destroy. At that time, the strength and equipment of the Central Red Army were very different from those of the attacking Kuomintang troops, and for a time the situation facing Yan'an was very critical.
However, at that time, if the CPC Central Committee had divine help, it strategically abandoned Yan'an, jumped to the outer line, and while holding Hu Zongnan's nose, constantly attacked and harassed him, making him tired of running for his life, resulting in heavy losses to the Kuomintang troops, but even the sweat of the CPC Central Committee was not caught. Because of this incident, there was also a gap between Chiang Kai-shek and Hu Zongnan, and the Kuomintang even suspected that Hu Zongnan was "all-in-one." In fact, it was not Hu Zongnan who was in the Communist Party, but his trusted personal secretary Xiong Xianghui, who was a Communist Party member lurking within the Kuomintang.
It was he, who took advantage of the opportunity of close contact with Hu Zongnan, that the CPC Central Committee grasped in a timely manner a series of intelligence, including the plan for attacking Yan'an approved by Chiang Kai-shek, the movements of Hu Zong's southern troops, and even Hu Zong's daily dynamics. Because of his excellent work around Hu Zongnan, he was known as the first of the "last three masters" of Longtan Sanjie, and was praised by Chairman Mao as "one person can top several divisions".
Xiong Xianghui not only changed the course of the Chinese revolution in this matter, but also saved the Chinese revolution once again as an important witness and participant in the days that followed.
In 1976, after a full decade of the Cultural Revolution, Deng Xiaoping was persecuted, and premier Zhou's death cast a dark cloud over the psyche of all those who cared about the Chinese revolution. For a time, the left became more and more arrogant. At this time, Chairman Mao's appointment made Xiong Xianghui, who had underground experienced for many years, feel a glimmer of hope. On February 3, after Mao Zedong's nomination and the politburo's approval, Zhang Chunqiao, who had previously ranked after Zhou and Deng, was overtaken by Hua Guofeng, and he, instead of Zhang, became acting premier of the State Council. Through close contact, he sensibly judged that Hua Guofeng was not a leftist figure, and quickly passed the news to Marshal Ye Jianying through his daughter. Since then, he has been in the middle of the mediation, acting as an intermediary as a bridge between Hua Guofeng and Ye Shuai. That was when the two joined forces to crush the Gang of Four.
It can be said that without him and without the action of smashing the Gang of Four, our country would not have carried out reform and opening up so smoothly, nor would it be able to re-enter the top of the world in this new century.
