A textbook example

Lin Fan was extremely happy. The hospital exit was right in front of him. He wanted to leave as soon as possible. The surgery had been a success and he was in a good mood. After all, he had helped to save someone with his own ability and that felt great.

"Hey, something's wrong." Then, Lin Fan stopped walking. The hospital security suddenly blocked all the exits of the hospital and all the cars that were entering or leaving the hospital had to be checked.

They had received the news that someone had pretended to be a doctor and entered the operation room. It was a serious offense and they didn't dare to take it lightly.

Lin Fan wore a mask and was thinking about how to leave the hospital. Just as he was thinking about it, the security officer saw Lin Fan and pointed at him. "The one wearing a mask, please stand right there."
