Grown children in China must visit their parents or potentially face fines or jail, a new law that came into effect on Monday says.
China's new "Elderly Rights Law" deals with the growing problem of lonely elderly people by ordering adult children to visit their ageing parents.
The law says adults should care about their parents "spiritual needs" and "never neglect or snub elderly people".
The regulation has been ridiculed by tens of thousands of Chinese web users.
Many across China are questioning how the law could be enforced, since it fails to spell out a detailed schedule dictating the frequency with which children should make parental house calls.
