After the anatomical instructors undergo the preservation process, they must wait at least one year before entering the laboratory for classes. There will be some residue of chemicals, skin, and other substances on their bodies during this period. Therefore, before the start of the experiments, students are guided to clean and tidy up the silent mentors' appearance. Although most students may initially feel fear or sadness when facing the silent mentors, the cleaning process helps students get to know the silent mentors. The various marks on the silent mentors' bodies represent different life experiences and journeys. In the end, students cover the silent mentors with clean white sheets with a sense of respect and gratitude, embarking together on the learning journey of the anatomy lab.
