Pregnancy brings new hope after Tianjin blasts

A woman who lost her 19-year-old son in the Tianjin warehouse explosion in August has conceived another child through in vitro fertilization.

Liu Yun'ai, 43, said her son, Cai Jiayuan, was among 104 firefighters who were killed following the massive chemical explosions at the port.

"The first few months after my son died were like hell for me," said Liu, who lives in a village in Hunan province. Working through her grief, she realized the best way to remember her son might be to have another baby. But she worried that conceiving naturally at her age might be problematic.
