On March 14, at about 4 pm, police officer Yang Zeru, the fifth brigade of traffic police, was on duty at the intersection of Guangzhou Road, Huju Road. Suddenly, a citizen on the side of the road reported that someone had fainted in front of him.

Officer Yang immediately went forward to check the situation. It turned out that a female college student from other places fainted to the ground. Her companion hugged her girl companion and said that they had just arrived in Nanjing. At noon, the two of them rode bicycles to visit Nanjing together. "She may have fainted because she didn't eat at noon to lose weight, and her blood sugar was too low. Another time she fainted because of losing weight, but this time she was in a direct coma." The girl companion said.

Later, the girl woke up and a passerby left a message. Because the ambulance couldn't come for a while, the traffic police stopped a taxi and sent it to the hospital for treatment.
