Well, three discoveries to be precise.
The situation happened shortly after Song Qingchun's holiday was over, on the fourth night after she returned to work at Station TW. Early that morning, the northern wind swept through Beijing, causing the temperature in the city to drop several degrees in just a few short hours.
When Song Qingchun left the hospital that morning, she took a detour home to grab a light yet warm feather blanket for Song Menghwa before rushing to her company.
That afternoon, Song Qingchun happened to run into Su Zhinian at the entrance to City Clubhouse. It was due to work that she was there. She had a document that she urgently needed to give to the station manager, who was there.
