Ying Guixin immediately became the first real murderer to be arrested. The detention center in the British Concession further arrested a number of suspects, who were identified by the foreign staff of Shanghai-Nanjing Railway Station and recognized the murderer Wu Fuming (real name Wu Fuming). Ying Guixin's home was searched and found a pistol with two bullets in it, which was found to be consistent with the warhead taken out of Song's body. Letters from Ying Guixin's home and Ying Guixin's telegram sent to Beijing from the telegraph office found that Hong Shuzu, the secretary of Premier Zhao Bingjun, had called Ying Guixin and said, "Destroy Song's honor and be properly prepared." On March 14, Ying Guixin replied to Hong Shuzu's "cold electricity" message, which read: "The leader of Liangshan bandits is in chaos on all sides, and the danger is very serious. An urgent order has been issued, trying to arrest him, begging to hand him over and waiting for him. " On March 18, Hong Shuzu replied to Gui Xindian: "Cold electricity will be done right away." On March 19, Hong Shuzu called again: "Things should be done quickly." At 2 am on March 2/Kloc-0, shortly after the assassination of Song, he sent a telegram to Hong Ying: "At 20: 40, the emergency order has been issued. Please report it first. " On March 2 1, a telegram was sent to Hong: "I learned that the bandit leader had been eliminated and there were no casualties in our army. It's comforting. Please forward it. " Wait a minute. As a result, Hong Shuzu, Zhao Bingjun and Yuan Shikai became the suspects behind the scenes. At this time, after negotiating with the British and French consuls, Ying Guixin and Wu Shiying were transferred from the trial court of the Shanghai Public Concession to the local authorities in China's own prison. Shortly after the handover, samurai Ying ate the poisonous steamed bread sent by Ying Guixin's friend and died suddenly in prison. Therefore, Cai Dongfan lamented in The Romance of the Republic of China: "It can be seen that the prisons in China are not as tight as the western arrest rooms, which makes westerners laugh. This is really regrettable. " Ying Guixin escaped from a prison robbery and went into hiding in Qingdao. After the failure of the Kuomintang's second anti-Yuan revolution, Ying Guixin began to expose himself and publicly sent a telegram demanding "rehabilitation of unjust imprisonment". Later, he openly went from Qingdao to Beijing to ask Yuan Shikai for a reward, asking Yuan to honor his promise to "destroy the song reward" and give him a medal and huge cash. Yuan wanted him to leave Beijing with a reward, but he couldn't be decorated publicly. Ying Guixin insisted that honor and money were indispensable, and finally angered Yuan and sent four great men to hunt him down. Gui Xin fled at the news and was hacked to death by Hao Zhanyi and Wang Shuangxi, officers of the military and political law enforcement departments, on the train from Tianjin to Tianjin on June 19 14. After the assassination of Song Dynasty, Prime Minister Zhao Bingjun resigned because of suspicion, and was soon transferred to the governor of Zhili (Tianjin). Ying Guixin was in charge of Zhili when he was killed on the train. As soon as he got the news of Gui Xin's death, he gave an order to arrest the murderer without asking Yuan, and complained to Yuan in a long-distance phone call: "Who dares to work for the president in the future?" ! "In less than a month, Zhao Bingjun was poisoned in Tianjin, and he bled to death.
