When it comes to the Battle of Menglianggu, everyone must know that Zhang Lingfu, the "rich and handsome" among the first-class generals, led the invincible reorganized 74th Division, which was extremely arrogant, but in the end it was completely annihilated by the East China Field Army. Of course, there are many reasons for Zhang Lingfu's failure, but one of the reasons that cannot be ignored is that he died in the "palace fighting drama". If you want to talk about this "palace fighting drama", you must first talk about Li Tianxia. 
Li Tianxia is a native of Shanghai, in today's words, he belongs to the rich second generation, with an innate sense of superiority, no matter what he has to take the first place, and he can't see others being better than him. Therefore, Li Tianxia's characteristics on the battlefield can be summed up in two points: one is to fight bravely, and the other is to like to compete with others for merit and rewards. The first point is of course a good thing, Li Tianxia is indeed a fierce general, especially during the Anti-Japanese War, he has participated in the Battle of Songhu, the Battle of Lanfeng, the Battle of Wuhan, the Battle of Changsha and other battles. However, the second point made him a little hateful, and it was precisely for this reason that Zhang Lingfu died Meng Lianggu. Li Tianxia and Zhang Lingfu have formed a relationship, and they have to start with one person, that is, Wang Yaowu. 
In 1925, Li Tianxia was admitted to the third phase of the Whampoa Military Academy, and Wang Yaowu was a classmate at the same time, and the relationship was also very good. After graduating, Li Tianxia rose all the way in the National Revolutionary Army, successively serving as platoon commander, company commander, and battalion commander, but this momentum came to an abrupt end in 1930. In the end, it was Wang Yaowu who helped, Li Tianxia had the opportunity to serve as the head of Wang Yaowu's subordinates, and Wang Yaowu also used him very much, from then on, every time Wang Yaowu was promoted to a level, he would let Li Tianxia take over his class, as if he was Wang Yaowu's first ** person. However, in 1939, when Li Tianxia was about to take over as the commander of Wang Yaowu's 74th Army, Zhang Lingfu was killed halfway. This Zhang Lingfu was originally Li Tianxia's subordinate, but he was young and promising, outstanding, brave and good at fighting, and was deeply appreciated by Wang Yaowu. After Wang Yaowu was promoted, according to the previous practice, the commander of the 74th Army should have been given to Li Tianxia, but Wang Yaowu gave it directly to Zhang Lingfu this time. Li Tianxia, who has always been competitive and competitive, was angry when she learned about it, this Zhang Lingfu was just one of my subordinates, and now he actually climbed on my head, which is unbearable! And what's even worse is that Zhang Lingfu is another arrogant person, often squeezing Li Tianxia, which makes Li Tianxia unbearable, so Li Tianxia has been looking for an opportunity to take revenge on Zhang Lingfu. 
In May 1947, after the start of the Battle of Menglianggu, Zhang Lingfu led the 74th Division to go deep into the army, wanting to use himself as a bait to attract the East China Field Army first, and then summon a large army to surround the Huaye Army from the outside and attack inside and out! This tactic is indeed reasonable, with the strength of the reorganized 74th Division, as long as it can withstand Huaye's attack, and when the large army comes, it still has a good chance of winning. However, Zhang Lingfu ignored one point, that is, whether his colleagues would cooperate with him. Zhang Lingfu also specially called Tang Enbo and asked Li Tianxia to come to help. But Li Tianxia wishes you were done sooner, how could she come to save you? So, only one regiment was sent over, and it was still waiting. Without reinforcements, Zhang Lingfu can fight again, how can he be Su Yu's opponent? In the end, the reorganized 74th Division was completely annihilated, and Zhang Lingfu was also killed. In this way, Li Tianxia's jealousy was victorious, but this behavior was unforgivable on the battlefield, so Chiang Kai-shek ordered him to be shot, but fortunately, someone interceded and exempted him from the death penalty. Later, Li Tianxia was depressed and spent 12 years in prison, who is to blame?
