What happened when calligrapher Yan Zhenqing commanded 200,000 troops to quell the chaos?

Twenty years later, Tang Xianzong and Chun Li ascended the throne, and the Tang Dynasty gradually recovered from the destruction caused by years of war, which was called "Yuan and Zhongxing" in history. To commemorate Yan Zhenqing's achievements in putting down the rebellion and setting up the release pond, Nanjing people built the release temple in Wulongtan. Fangsheng Temple was renovated in the Song, Yuan, Ming and Qing Dynasties. In the third year of Xianfeng in Qing Dynasty (A.D. 1853), the Taiping Army captured Nanjing, and the Fangsheng Temple in Wulongtan was also destroyed by war. In the sixth year of Tongzhi (AD 1867), Tu Zongying, Zeng Guofan's favorite pupil, was promoted to Jiangning magistrate. At this time, Nanjing has just experienced a catastrophe, which can be described as wasting time. Tu Zongying showed kindness and could not bear to kill him. He built an ancestral temple on the former site of Fangsheng Temple and inscribed a plaque in memory of Yan Zhenqing. Because Yan Zhenqing was once named Duke Lu, the ancestral hall was also named Duke, and it has been preserved to this day. 1982, Road Show Temple was listed as a cultural relic protection unit in Nanjing.
