S1E1: Long Time No See

The Shili Tai Fire and Rescue Station is in a festive scene. Suddenly the alarm rang, and firefighters were dispatched immediately. In the early morning, ER doctor Xu Qin had just returned from the emergency room after a major operation. A few firefighters covered in mud rushed in, begging her to treat his comrade who has a toothache. When she told the man to remove his mask, the man turned away and left the emergency room.
