On April 29, 2008, a warm air mass in the Hetao region was moving towards Beijing. The newspapers said that the sunny weather was suitable for outdoor activities. At 5 pm, the temperature measured by the Nansuburban Observatory reached 27.8℃. It was still bright at around 6 pm when Gaogao went out.
The training ended at 6 pm. He should have rushed to the cafeteria for dinner, but he felt "particularly twisted" inside, so he went straight out of the sports school. There were already many cars on the road. The important news broadcasted on the radio that day was about the train collision tragedy that happened in Shandong. However, Gaogao did not hear any of these. He boarded a bus going north.
