On November 28, 1948, the elder Jiang telegraphed Du Yuming to Nanjing for a meeting to study how to relieve the Huang Wei Corps. Du Yuming did not dare to be sloppy, and immediately flew to Nanjing, but was unexpectedly told that the meeting would be held in the afternoon. In this way, Du Yuming had nothing to do all morning, and just when he was about to go to Gu Zhutong to talk, his disciple Guo Rujie came over and warmly invited Du Yuming to his home.
Guo Rugui graduated from the Huangpu Fifth Term, joined the Communist Party in 1928, and after the defeat of the Great Revolution, Guo Rugui lost contact with the organization. At the recommendation of his cousin Guo Rudong, he went to the Japanese Non-Commissioned Officer School to study, and after returning to China, he entered luda for further study, when the principal of luku university was concurrently appointed by lao Jiang, and Guo Rujie once again became a protégé of Tianzi. During lu university's further studies, Guo Rugui ranked first in all his achievements, which was favored by Lao Jiang. Soon after, the "Central Training Regiment" was launched, with Old Jiang concurrently serving as the head of the regiment, and Guo Rugui was appointed deputy captain.
After the outbreak of the War of Resistance Against Japan, Guo Rugui came to Chen Cheng's side to advise him, and in the Battle of Songhu, the Battle of Wuhan and the Battle of Changde, Guo Rugui made many very insightful suggestions, which were appreciated by Chen Cheng and regarded as his confidants. During the Battle of Changsha, Guo Rugui served as the commander of the Provisional 5th Division, and after taking office, he found that the division actually had only more than 3,000 people, but more than 7,000 people were reported, and the remaining more than 4,000 vacancies were eaten by officers at all levels. Only then did it become clear that the reason why the Nationalist army lost more than won less in the frontal battlefield was not only the reason for backward equipment and command mistakes.
After the victory of the War of Resistance Against Japanese Aggression, the receiving officers sent by Lao Jiang even took advantage of the opportunity to take advantage of the opportunity to seize the fat oil one by one, and Guo Rujie was very unaccustomed to this. Soon after the Liberation War broke out, Guo Ruzhi contacted Dong Biwu through his old connections and became a red agent of our party lurking around Lao Jiang and Chen Cheng. With his excellent staff skills, Guo Ruzhi was appointed by Chiang Kai-shek as the director of the Third Department in charge of operations. He took advantage of his position to send top-secret information to our Party on many occasions. The reorganized 74th Division was destroyed, Huang Baitao and Huang Wei's corps were besieged, and Guo Rugui made a contribution.
This time When Du Yuming came to Nanjing, Guo Rugui guessed that it must be related to the siege of Huang Wei's army. So he warmly invited him to his home as a guest, planning to learn about Du Yuming's next battle plan from the side. Unexpectedly, Du Yuming was very cautious and kept silent about the situation on the battlefield of the double stack. After coming out of Guo Rugui's house, Du Yuming went directly to see Lao Jiang, reported that Guo was a co-spy, and asked Lao Jiang to quickly send someone to arrest him.
Du Yuming's words surprised the old Jiang, Guo Ruzhi was responsible for drawing up the battle plan for a major battle, and the specific deployment of the Battle of Xu Beng was even more from his hand, if he was a co-spy, this battle could not be fought. However, Old Jiang did not believe that Guo Rujie was a co-spy, so he asked Du Yuming what evidence he had. Du Yuming replied: Guo Rugui is in a high position, but his family is surrounded by walls, and the sofas in his home are patched, so clean and honest is not the Communist Party, what is it?
Old Jiang saw that Du Yuming did not have any substantial evidence at all, and reprimanded him for not catching the wind and shadows anymore. Du Yuming saw that Lao Jiang had this attitude, so it was not good to say more, but he asked to meet with Lao Jiang alone when the afternoon meeting was held. In the afternoon meeting, the large conference room was in charge of Gu Zhutong and Guo Rujie, and Du Yuming was called into the small conference room by Lao Jiang. Du Yuming confessed to Lao Jiang that the only way now was for Huang Wei to contain the People's Liberation Army in Shuangdui and withdraw Xuzhou's troops to the areas of Mengcheng, Woyang, and Fuyang, so that he could also save more than 200,000 men and horses in the three corps.
In the end, Lao Jiang agreed to Du Yuming's proposal to withdraw from Xuzhou in an all-round way, which Guo Rugui did not know. After Du Yuming returned to Xuzhou, he immediately deployed the retreat and ordered all the departments to carry seven days of supplies, five hundred kilometers of fuel and ammunition, and not to supply them halfway before reaching Fuyang. Du Yuming had thought that by hiding from Guo Rujie, he could calmly retreat. However, the senior officers leaked the news of the evacuation in advance for their own selfish interests, which caused great panic, and many people ran south with the troops, resulting in serious road blockages and a great reduction in the speed of the march. Just after running to Chen Guanzhuang, he was chased and surrounded by Hua Ye, and Du Yuming's army was defeated and captured. Soon after, Guo Rujie revolted in Yibin, and in his later years enjoyed the treatment of deputy corps, and died in 1997 at the age of 90.
