Started in November 2020, the service is available in several residential communities in the Gongshu district of Hangzhou, Zhejiang province. More than 800 seniors have received the service, said project leader Li Ting. The service is provided by JiuJiu Zhu Lao, a local tech company dedicated to smart care for seniors.
