The little radish head, whose real name is Song Zhenzhong, is a native of Pizhou, Jiangsu Province, and his father Song Qiyun and mother Xu Linxia are both communists. In 1929, the couple was assigned by the organization to work next to Yang Hucheng, and Song Qiyun served as Yang Hucheng's secretary and participated in the "Xi'an Incident". Shortly after the peaceful settlement of the "Xi'an Incident", Lao Jiang used power to make Yang Hucheng lose control of the Northwest Army and force him to leave the country. After the Outbreak of the War of Resistance Against Japanese Aggression, Yang Hucheng repeatedly called Old Chiang kai-shek to ask to return to China to participate in the War of Resistance Against Japanese Aggression, but all of them were rejected.

In December 1937, General Yang Hucheng, who was bent on resisting Japan, secretly returned to China, but unexpectedly arrived in Nanchang and was arrested and imprisoned by military agents. After Yang Hucheng was placed under house arrest, Song Qiyun and Xu Linxia were in an extremely dangerous situation, and for the sake of safety, the organization transferred the two back to Yan'an. In November 1939, Song Qiyun was sent by his superiors to do united front work in Sun Weiru's Fourth Army, serving as a major general counselor and political instructor. At the end of 1941, Song Qiyun's identity was learned by the secret agents of the military command, and he was immediately arrested, along with his wife Xu Linxia and his 8-month-old young son Song Zhenzhong.
For the next 8 years, Song Qiyun's family was imprisoned in the Bai Mansion, Zha Di Dong, and the Guizhou Xifeng Concentration Camp. Due to the harsh environment of the prison and long-term malnutrition, Song Zhenzhong was skinny and bone-covered, and his small body had a big head, and the victims in prison lovingly nicknamed him "Little Radish Head". On the evening of September 6, 1949, Yang Jinxing, a secret agent of the military command, led people to kill Yang Hucheng's father and son and Song Qiyun and his wife with daggers, and personally killed the little radish head, only 24 days after the founding of New China.
After the liberation of Chongqing, the remains of Xiao Radish Head were found, his two small hands clutched dead to his chest, holding a small pencil given to him by General Huang Xiansheng, which was the most precious gift he received during his 8 years in prison. This scene made the people present tearful and indignant, and they secretly vowed that they would definitely bring the murderer Yang Jinxing to justice and avenge the heroic martyrs who died. Yang Jinxing, whose hands were stained with the blood of revolutionary heroes, personally killed more than 300 people, and the means were extremely cruel. Ignoring the bitter pleas of the martyrs Wang Zhenhua and Li Jieshuang, he brutally killed their one-year-old sons, Wang Youhua and Wang Xiaohua, in person.
Agent Yang Jinxing
After the liberation of Chongqing, the local police immediately issued a arrest order for Yang Jinxing, but the executioner seemed to have evaporated from the human world, and there was no news. In August 1953, China conducted the first census, and Yang Dafa, a villager in three villages in Qingju Township, Nanchong, Sichuan Province, attracted the attention of the census takers. He said that his hometown is in Guang'an, 4 years ago came to Nanchong to do small business, on the way encountered robbers property was robbed, helplessly settled in Qingju Township. The census personnel immediately sent a letter to verify, and as a result, Guang'an replied that there was no such person, and the census personnel immediately reported the situation to the local public security organs.
The public security personnel immediately launched an investigation and found clues at the post office, Yang Dafa's wife Tian Dejun repeatedly wrote letters to her mother's family and mailed a lot of property, and the public security personnel traced her mother's home. Tian Dejun's mother said her daughter was married to a man who was on an errand at the Chongqing Garrison Headquarters. Subsequently, the public security personnel came to Gongdelin with a photo of Yang Dafa and let the big secret agents Xu Yuanju and Zhou Yanghao identify it, and the two quickly recognized that the person in the photo was Yang Jinxing, the former warden of baigongguan prison.
For the sake of safety, the investigators also took the photo to Luo Guangbin and Li Yinfeng, who had escaped from the White Mansion, and others, and they unanimously determined that the person in the photo was the executioner Yang Jinxing. It turned out that Yang Jinxing knew that he could not escape the blame, and after the founding of New China, he came to Qingju Township with his wife Tian Dejun in anonymity and hid it for four years. Unexpectedly, the horse's feet were exposed in the census, and after the public security personnel determined his identity, they immediately arrested him and executed the executioner after the public trial.
