How to evaluate Li Zongren?

In the narrative of "Memoirs of Li Zongren", Li Zongren still admires himself, and there is basically no review and introspection, so it is inevitable that he is suspected of Wei. But judging from historical events, it is fair and objective on the whole. As one of the three giants of New Guangxi, Li Zongren defended Guangxi, devoted himself to the Northern Expedition, advanced into the Central Plains (unsuccessfully), and finally won the title of acting chairman of the Kuomintang, which can be described as a retirement. Speaking of Li Zongren, the other two have to say. Li Zongren, Huang and Bai Chongxi, the three generals of Guangxi, have their own strengths and strategies. From the initial fragmented, they finally came together for decades, never giving up, learning from each other's strengths and helping each other, which is also a valuable model in the history of China. The close cooperation of the three of them made the reunification of Guangxi and the New Deal become a reality. Since the establishment of the New Guangxi Department in Guangxi, it has been trying to break out of its own world. But now the situation has changed, and Chiang Kai-shek has always been invincible in the Chiang Kai-shek War and the Central Plains War. The Battle of Taierzhuang (Xuzhou Battle) is a masterpiece of Li Zongren's life, which wiped out about 20,000 Japanese troops, and achieved the greatest victory of China army in the early War of Resistance against Japanese Aggression, greatly inspiring the morale of the military and civilians throughout the country. Among them, the national righteousness of the Sichuan Army and the abandonment of personal grievances by the Northwest Army are all good stories. During the war of liberation, the strategic mistakes, the fatigue of soldiers and the defects of commanders caused the situation to turn upside down. In spite of this, Li Zongren and Bai Chongxi are still actively engaged in fighting. On the south bank of the Yangtze River, they negotiated, forced the palace, fought and made a series of plans. Even during their retreat to Guangxi, they still managed hard, but after they finally fled the United States, they still wanted to make a comeback. Throughout his life, he was ambitious, ambitious, and throughout his life, he approached the goal step by step. Although it is not completed, it is still a hero.
