On January 16, the K1628 train from Fuzhou to Chongqing North received requests for help twice from a passenger with a baby in his arms and once from a passenger with a 4-year-old child. The conductor and the police wanted each other to get off the train to help, but the three pairs of parents insisted on staying on the train because it was difficult to buy tickets during the Spring Festival travel season.

At about 10 o'clock on January 17, the eight-month-old son of Chongqing passenger Xiao Sun and his wife suddenly had a high fever. The two first-time parents were at a loss and found the train staff for help. After the train conductor and the police learned about the situation, they immediately went to check and learned that Xiao Sun's son had a fever before getting on the train, and his condition worsened after getting on the train. The conductor took a fever-reducing patch from the train infirmary and put it on the child. He suggested that Xiaosun and his wife get off the train at the station ahead and go to the hospital for treatment. But Xiaosun and his wife believed that their child's condition improved after applying the antipyretic patch, and it was "hard to get a ticket" during the Spring Festival travel period, so they rejected the train conductor's suggestion.

On January 18, as the train was returning to Fuzhou, the conductor received requests for help from Putian passengers Xiao Liu and his wife and Hubei passengers Xiao Hao and his wife. A 1-year-old baby boy and a 4-year-old girl had fevers. But the two young couples also ignored the bus captain’s advice and insisted on continuing their journey. "Children take a long time to recover from illness and often relapse. It is not suitable for children to travel long distances while they are sick." "Anti-pyretic patches can only temporarily protect the brain and cannot be used to reduce fever. Timely treatment is required." Train conductor Chen Xiurong suggested that passengers who encounter similar situations should distinguish the seriousness of the matter.
