"I thought about it at that time, now newspapers and magazines are silent, haven't they said a lot about acts of bravery? Everyone saw it, I didn't knock him down, will there be no problem?" The incident drew the attention of many netizens, revealing the gap in educational resources. Some netizens asked the traffic police department to "return the car to the owner", which brought considerable interference to the authorities handling the case during the investigation phase. Deputy Mayor of Yulin City and Director of the Public Security Bureau, Xu Jianzhong, also required the traffic police department to quickly ascertain the truth, enforce the law impartially, and handle the matter seriously and according to the law. In the post, "Zhang Du" compared himself to the Guangxi version of "Xu Yunhe". He repeatedly regretted helping the old man and called for society to restore his innocence and fairness. On March 5, a reporter from a Yulin newspaper also published an article titled "Collision or Assistance? Baise farmer Zhang Du has been troubled recently" on Hongdou Community and his personal blog. On March 7, in the accident inquiry room of the Directly Subordinate First Brigade of the Yulin Municipal Public Security Bureau Traffic Police Detachment, Zhang Du continued to insist emphatically that he was not the perpetrator: "I have no regrets for my conscience!" To completely break his "defense line", the police officers retrieved the electronic surveillance video near the accident scene: the video showed that when the involved elderly person crossed the road, he collided with the left front corner of a fast-turning minivan. The old man was knocked down on the spot. This hit-and-run vehicle was precisely the one driven by Zhang Du.
