A laryngeal mirror was a small mirror with a long handle, and it looked kind of like a longer and larger ear digger. The doctor would pull the patient's tongue and shove the laryngeal mirror into the patient's throat, and they were able to get plenty of information by doing so.
Laryngeal mirrors also came in various shapes and sizes, and some of them were thicker than the others. It was not a very comfortable examination method, but it did not take long.
Ren Qi took a laryngeal mirror pack from the nurse. He did not open it immediately. Instead, he rested his hand on the packaging and tried very hard to recall everything he had learned about laryngeal mirrors.
