At the beginning of the civil war, Liu Ruming's 2nd Group Army was reorganized into the 4th Appeasement Zone, and Liu served as the deputy director of the Zhengzhou Appeasement Office and the commander of the 4th Appeasement Zone, stationed in Kaifeng and other places. However, in the end, only two armies were retained, the 55th Army and the 68th Army, which were respectively commanded by his brother Liu Ruzhen and Cao Fulin, the former commander of the 55th Army, and the original 69th Army was streamlined, and the army commander Mi Wenhe was reappointed as the commander of the 181st Division. There was internal discord, and Mibe did not listen to the dispatch.
In 1946, Liu Bu fought with the Shanxi, Hebei, Shandong, and Henan People's Liberation Army many times, and the battle continued, without victory, and more than 16,000 people were annihilated.
In January 1947, the first department besieged Jinxiang, Liu Ruming ordered his brother Liu Ruzhen to lead his troops to relieve the siege, and was defeated by 4 regiments.
In March of the same year, Chiang Kai-shek deployed a Yellow River defense line with heavy troops, intending to block Liu Deng's army in the area north of the Yellow River.
On June 30, Liu Deng's army set up a battlefield along the Yellow River for more than 300 miles, carried out a forced crossing, and broke through the Yellow River defense line from the front in one fell swoop, and Liu Ruming's troops were vulnerable. Xuzhou "Suppression Chief" heard that Liu Deng had crossed the Yellow River, and hurriedly asked Liu Ruming about **, Liu Ruming actually replied, only heard that ** had fired hundreds of shells over, as for whether he had crossed the river, he didn't know. Later, Liu Ruming's troops retreated to Yuncheng and Heze, holding on and waiting for help. On July 10, Yuncheng was broken by the People's Liberation Army, and all the troops were annihilated, only Cao Fulin fled back to Kaifeng alone.
In June 1948, he was transferred to the deputy commander-in-chief of the Xuzhou Bandit Suppression Headquarters and the commander of the 4th Appeasement Zone. Later, Chiang Kai-shek wanted to implement the Huai River defense strategy, and when he hesitated, Liu immediately went south, and did not hesitate to leave the 181st Division Mi Wenhe as a bait and assigned it to Qiu Qingquan's department. He also pretended to promise Liu Zhi to leave a division to defend Suxian, but when he passed through Suxian County, he didn't get off at all and went directly to Bengbu. This move was criticized by the generals, and the generals in the direction of Xuzhou all called Liu Ruming "veteran oil".
On December 1, 1949, the Huaihai Campaign was in full swing, and the 4th Appeasement Zone was reorganized into the 8th Corps, with Liu Ruming as the commander. Chiang Kai-shek ordered him to lead his troops to march in tandem with Li Yannian of the 6th Corps, and went north to rescue Huang Wei's corps, and even killed them. However, in order to preserve his strength, Liu Ruming adopted the tactics of fake fighting to deceive Chiang Kai-shek, and Chiang scolded him for fighting a "slippery battle". At this time, in order to show his loyalty to Chiang, Liu Ruming betrayed his former colleagues of the Northwest Army, Sun Liangcheng and Wang Qinghan, and the communist Zhou Hao, who had persuaded him to surrender in the future, and Chiang Kai-shek did not hold him accountable for his ineffective fighting.
In January 1949, he was transferred to the Beijing-Shanghai-Hangzhou Garrison General Headquarters as Deputy Commander-in-Chief and Commander of the 8th Corps. Defending the Yangtze River, the People's Liberation Army crossed the river with the sound of artillery, and its troops retreated. In April, he was transferred to the post of commander-in-chief of the Fujian-Guangdong border region and commander of the 8th Corps. His troops were either annihilated or surrendered to revolt, and there was not much left. went to Taiwan, and was dismissed from office on October 22.
Liu Ruming died on April 28, 1975 in Taipei, Taiwan. In his later years, he wrote articles such as "Memoirs of Liu Ruming", "Memories of Comrades-in-Arms in 77", "77 Anti-Japanese War and the 29th Army" and other articles. In the book, he expressed his heart's desire: "We are still separated from God, and I will go to your spirits one by one to pay homage." ”
Liu Ruming, who lives in a simple place, is not good at socializing, rarely socializes, is thoughtful, scheming, conspiratorial, frugal in life, and filial piety to his mother. He also has a mild temperament, loves the best soldiers, treats people generously, pays attention to persuasion, and punishes less, and is often called "Liu Shanren" in the army, so the discipline of his troops is lax, and many harmful phenomena occur. Liu Ruming fought calmly, resolutely, and defended. Politically conservative, although dissatisfied with Chiang Kai-shek, he was extremely loyal. In short, Liu Ruming is an out-and-out old soldier from the army. History
