Speaking of this Pang Dayang, he was one of those travel companions who planned to go to Shandong with Li Hanxiao and others. Due to the train accident, they couldn't make the trip and he was injured and sent to a local hospital for treatment. Fortunately, the injuries weren't serious, and he stayed at the local hospital for half a month, claiming he was fully recovered upon returning to Beijing. Unexpectedly, shortly after returning to Beijing, the pain recurred. When he went to the emergency room at the hospital in Beijing, it was discovered that the equipment at the previous hospital had failed to detect a residual blood clot in the brain. He was taken to the operating room for emergency surgery that night, with Shen Jiayin on duty in the operating room.
