Chen Yan, 24, works at a senior care service center in Pidu District, Chengdu. The average age is over 85 years old, and most of them have Alzheimer's disease.

Chen Yan ignored her family's objections when she was in vocational school and chose to major in elderly services and management. She also has her own "methodology" on how to make the elderly happy and change their perspective. "As people get older, you actually have to change your perspective and enter their world"
