On the eve of the Mid-Autumn Festival, Shen Nian'an took her three-year-old daughter on a train back to their hometown. To make it easier for the child to rest, she used a hard-seat ticket to place luggage. Passenger Sun Xiue demanded that the seat be cleared, and a dispute and tug-of-war broke out between the two sides, during which the child was bumped and injured. Shen Nian'an calmly collected evidence, handled the dispute through mediation, did not ask for compensation, and only hoped that the other party would treat passengers with children kindly. After this incident, both of them changed, and years later they met by chance and reconciled, telling everyone that train tickets represent rules, and people should communicate well when things happen.
