Song Qingchun managed to squeeze to the front of the crowd. While she waited for the train to arrive, she pulled out her phone to check her messages.
In less than a minute, the platform started to fill again.
The speakers announced that the train would be arriving soon. Song Qingchun put away her phone to prepare to board the train. Before Song Qingchun realized what was happening, she was shoved forcefully from behind and sent flying beyond the yellow line.
The incident was so sudden that Song Qingchun only managed to hear people yelling, "Be careful."
She was about to tumble into the rails propelled by the momentum when someone from the crowd reached out to grab her arm. Amid the cacophony, she was pulled back into the crowd.
The person's first instinct was to save her, so he had not measured the force of his pull. Song Qingchun crashed into his chest and both of them collapsed to the floor. Several seconds later, the train sped into the station.
