Chinese Art Activities or Combined With Peer Group Participation on Psychological Well Being

The goal of this trial is to evaluate the effects of two interventions : routine care plus Chinese Art Activities(+CAA) and routine care plus Chinese Art Activities combined with Peer Group Participation (+CAA+PGP) on psychological well-being, loneliness, happiness, relaxation, and salivary cortisol levels in elderly participants (aged 60-85, new residents with ≤1 year of stay). The main questions it aims to answer are: * Does the +CAA intervention improve psychological well-being and related outcomes compared to routine care? * Does the +CAA+PGP intervention provide additional benefits over +CAA alone? Researchers will compare three groups (Group A: +CAA, Group B: +CAA +PGP, Group C: routine care) to see if the interventions lead to immediate and sustained improvements in the measured outcomes. Participants will: * Undergo baseline assessments of psychological well-being(PWB), loneliness, happiness, relaxation, and salivary cortisol levels. * Receive their assigned intervention over three sessions within one week (Monday, Wednesday, Friday). * Complete outcome measures 30 minutes before and after each session. * Participate in a final follow-up assessment one week after the last session to evaluate sustained effects.
