Such centers for the elderly, located in communities, providing meals, medical services and bathrooms, are getting more popular in Shanghai, as young people become busier with work and cannot take care of their parents during the day. At present, there are more than 300 such daycare centers in Shanghai, and 20 new centers will be built this year. [Photo/CFP]
