Because of the reminder of the book friend Night Whisper Miaohan, I found that this work was too influenced by "Guardian", especially in terms of ideas, and after careful study, I decided to revise it again.

Because this is a work of practice, the primary purpose is to ensure the quality of the work, and we apologize for the inconvenience caused to readers

Originally, I should have started to revise it last year, but at first I didn't have time because I was about to graduate, and then I was looking for a job, until I finally settled down at the beginning of this year, and I encountered the medical practitioner exam again
