In the early morning of April 24, the second and third field armies of theChinese people's Liberation Army crossed the Yangtze River and entered Nanjing.At that time, the Kuomintang troops in Nanjing had retreated. After the PLA'sleading troops entered the city, they pursued forward. They found that there wasanother Kuomintang army in the cemetery, but this army was not a regular army ofthe Kuomintang, but a guard guard guarding Sun Yat Sen's mausoleum. Afterlearning of this situation, the superior leaders of the people's Liberation Armythought that the Gongwei troops guarding Zhongshan Mausoleum should be differentfrom the Kuomintang troops participating in the civil war. Then, the 105thdivision of the second field army sent a regiment political commissar LiuZhicheng to lead a group of soldiers into the cemetery. After arriving at thecemetery, they negotiated with fan Liang and other persons in charge of theGongwei office. Both sides unanimously decided that the people's Liberation Armywould be stationed in Zhongshan Mausoleum, Ming Xiaoling Mausoleum, LingguTemple and Zijinshan astronomical observatory.

Then, Liu Zhicheng and other people's LiberationArmy leaders, led by fan Liang, boarded Zhongshan Mausoleum and inspected thememorial hall, stele Pavilion and mausoleum gate of Zhongshan Mausoleum. Theyfound that there was no damage. At that time, the food supply of Gongwei brigadecould not be maintained, and there was still a lack of food.

In the early days of liberation, some people who did not know the truthlistened to the rumors and thought that they could occupy the state property atwill after liberation. Some people gathered in public to illegally cut down theforest, especially in the back of the mountain. Not only did some people notlisten to persuasion and education, but they dared to surround and beat themembers of the Gongwei guard. Zhang Wensheng, the monitor, and Zhai Wenwei, themember of the Gongwei guard, were all injured. Illegal logging was particularlyrampant at night, and Dai Yuanzhen, a member of the team, was injured by a handgrenade when he was on patrol. In order to strengthen the protection ofZhongshan cemetery, the CMC decided to send the PLA to cooperate with the archguard team to strengthen the patrol. Since August 1, Yao erjue and Li Wuben ledthe public security forces to guard the forest together with the members of theformer arch guard. They also arrested 11 criminals, including Feng Qibao, wholed the illegal forest felling, and escorted them to the people's Government often districts to deal with them. As a result, the bad elements who illegallyfelled the forest in the cemetery were attacked. After September, the wind ofillegal forest felling gradually subsided.
