The medicine bottle have be tampered with

She didn't seem to see him. Feng Sheng was in a hurry to deliver the food to Yi Yifeng, so he didn't call out to her. When she got to the doctor's office, she saw Yi Yi was staring blankly at the two medicine bottles on the table. She picked them up, put them down, picked them up again, put them down again, and after a few tries, she closed her eyes and picked up the medicine bottle on her right hand and walked into the operation room.

He walked over to Yi's desk, put the food on the table, picked up the medicine bottle, and looked at it. He turned it slightly, and the label on the bottle fell off. There was another label below it, and although he had never studied medicine, he always knew in common sense that there was a difference between the two chemicals on the label. "No, the label on this bottle is a later one, Yi, do you know?"
