Recently, on the way back to the station after a first aid mission, Zhang Lei's ambulance team of the western emergency center station received a new instruction from the dispatch command center. A patient injured in a car accident needed first aid. The crew immediately turned around to the accident. On the way, the doctor Zhang Lei contacted the scene by phone, asked about the patient's condition and gave medical emergency guidance in time. The crew soon arrived at the scene of the accident. There were police officers from Xicheng District supporting the Mentougou disaster area maintaining order and forming a "protective circle" around the patient. They ensured that the patient would not be injured again and assist the ambulance to come to rescue.

The medical staff came to the patient with first aid equipment and carried out a physical examination. The patient was conscious and his vital signs were stable. There was an open wound on his right upper limb, with severe bleeding, and small abrasions on both lower limbs. There were no injuries or fractures found in other parts. Dr. Zhang Lei quickly diagnosed that the patient's main injury was an open laceration of the right elbow joint with abrasions on both lower limbs. During the diagnosis, nurse Wang Mengtian had prepared the trauma emergency supplies, and the doctors and nurses cooperated to disinfect and debride the patient's wound. The wound was bandaged with sterile dressings under pressure, and fixed with a triangular towel. Later, the patient was transferred to a relevant hospital for further treatment.

During the ambulance transfer, the emergency personnel learned that the patient had just been saved by rescuers down the mountain from a village washed away by flash floods. He was hit by a speeding electric bike on the way to a relative's house.
