"Stop right there. Who are you and what do you do?" One of the Interpol officers asked coldly.
Cui Yong looked at him calmly and said, "I'm here to change my patient's dressing."
Interpol sized up Cui Yong carefully, then checked Doctor Wen Song's work pass. They asked Cui Yong to take off his mask. Seeing that his work pass was identical to his, they turned their attention to the medical cart.
They examined the car inside and out, but found no dangerous items or guns. They continued to examine Cui Yong.
Cui Yong asked in confusion, "Do police officers have to be so strict? I'm his doctor. I'm just here for a ward round."
"This is a special situation. If someone wants to kill the victim, we can only follow the rules and procedures!" the Interpol officer said calmly. They did not find any guns or dangerous items on Cui Yong's body, so they opened the door and let him in.
