Hangzhou, China (CNN) The odd collection of voices cuts through the cold Beijing air, the sounds emanating from a small, unremarkable back room. Inside, there's 20 or so people, most in their sixties and above. They're singing somber songs from the Chinese revolution, painfully and endearingly off-key. They call themselves a choir, but in reality, they're not there to sing. They are there to help one another grieve. Each person in the choir is a parent of an only child, and each person's only child has died. "I will never get rid of the pain," says Yang Chunhai. His son died of leukemia last year at just 31 years old.Parents who've lost their only child form choir for supportLawyer says one-child policy was financially lucrative for provinces
