Synopsis: 1948 In late autumn, the battlefield in the Central Plains was filled with smoke. The Central Plains Field Army of the People's Liberation Army successively conquered Zhengzhou, Kaifeng and other central plains towns, the East China Field Army annihilated the Kuomintang Yellow Corps, and the Kuomintang Xuzhou garrison Herry Liu Group hastily adjusted its deployment. In order to smash the strategic attempt of Herry Liu Group and strive to annihilate Herry Liu Group on the spot, the Central Military Commission sent an urgent telegram to the Central Plains Field Army to seize Suxian County and cut off the Xubang line. For a time, Suxian County, located between Xuzhou and Bengbu, became an important pawn in the Huaihai Campaign. The Central Plains Field Army, which had just conquered Zhengzhou and Kaifeng, was ordered to March in the direction of Xuzhou day and night. Liu Changyi, deputy commander of the third column of the Central Plains Field Army, led his troops forward and was stopped by Kuomintang tanks outside Suxian County, causing heavy casualties. Decisively quit the battle, sent a special service company, and found out that the enemy who blocked it belonged to the Kuomintang Zhang Traffic Police 16 Corps in Suxian County. Before the battle began, he was blocked by enemy tanks. Decided to thoroughly understand Zhang's deployment of the city defense in Suxian County, so as to make full preparations before the war for attacking Suxian County. Liu Changyi's idea of attacking Suxian coincides with the strategic intention of the military commission chief. Under the orders of the Central Military Commission and Chairman Mao, "The sooner the better, the more urgent the better", he personally led a team to disguise himself, which not only thoroughly understood Zhang's urban defense deployment in Suxian County, but also "stole" a car full of shells. Zhang was very angry at the theft of the armory and quickly won the Suxian Railway Station. When the armory was stolen and the railway station was occupied, Zhang began to realize that he was no ordinary opponent.
