China’s “Shidu” older adults—those who lost their only child—face unique vulnerabilities in a culture that emphasizes filial support. This paper presents an ethnographic study of a telecare call center in Shanghai, where 19 telecaregivers support over 20,000 Shidu older adults via remote monitoring and check-in services. Drawing on 200 h of fieldwork and 12 in-depth interviews, we examine how the Chinese value of renqing (empathic humaneness) influences telecaregivers’ day-to-day work, from software usage to personalized care. Our findings reveal that telecaregivers creatively combined proprietary digital platforms with everyday tools (e.g., WeChat) to address system gaps, driven by renqing-inspired commitment to older adults’ well-being. We highlight design opportunities—such as culturally-grounded messages, fairness-oriented workload monitoring, and empathy-focused user interfaces—to embed renqing while ensuring equitable treatment. By underscoring the critical role of sociocultural context in shaping technology use in emerging caregiving models, this work contributes new insights into relational care and implications for human-computer interaction (HCI) researchers and designers developing technology that balances ethics with fair eldercare services.
