Families of detained Chinese Christians cling to faith in legal limbo

Clasping her hands together in prayer, four-year-old Huanle tells God she misses her mum, whom she hasn't seen since Chinese authorities raided their home last year in a crackdown on their unregistered church. Last October, Chinese authorities cracked down on the Zion Church, one of the largest underground churches in China, detaining more than 20 of its members, including 43-year-old Wang, Huanle's mother.
