Wang Hanlin said that choosing music therapy as a career requires a genuine desire to help others. For example, when he learned that some elderly residents were in pain, he encouraged them to channel their emotions into songwriting as a way to cope. Without a true passion for this work, he feels that one may not be suited for the field, and would miss out on the joy it brings: "From the age of 60 and beyond, accompanying the elderly through their later years and forming deep connections with them provides invaluable energy, knowledge, and guidance — wealth that cannot be measured in monetary terms."
