The first is the time difference from the discovery of Chen Jinxiu's poisoning to first aid and reporting. According to Chen Chuanzhou, their family went to the public market together to attend the party at 6 pm, leaving Chen Jinxiu alone to watch the house. When I got home around 10:00, the door was locked and no one answered the door. When the door opened and entered the house, Chen Jinxiu was already lying on the wooden bed. When they saw the suspicious medicinal soup on the table, they realized that Chen Jinxiu might have committed suicide, so they invited Dr. Zhang for treatment at around 11 o'clock, but they were unable to recover.
After another 30 minutes, they reported the case to the police station. At this time, Chen Jinxiu seemed to still have a pulse. Investigators used their human flesh search ability to find the location of Dr. Zhang, and compared the location of Chen's family provided old picture restoration in the news materials with the doctor's information in the 1954 Taiwan Provincial Physician's Name Book. Fortunately, at that time, there was only one physician surnamed Zhang who practiced in Zhongshan Road, Hsinchu City. Zhongshan Road was only a 5-10 minute walk from the deceased's West Road.
If it was necessary to dig up Dr. Zhang who had already gone to bed, it would take no more than 30 minutes at most. After all, life is at stake, and doctors won't love to stay in bed like I do (covering my face). Of course, it is possible that the Chen family was in chaos for a while, and when they recovered, a lot of time had been lost. However, it is also possible that the Chen family spent a lot of time "processing" the scene.... Although the communication at that time was not as developed as it is now, it seems that it was not too far-fetched to find a doctor more than an hour after the abnormality was discovered.
