A woman who lost her son, a fireman, during the deadly explosions in Tianjin last year has conceived another child after undergoing in-vitro fertilization (IVF).

Liu Yun'ai said she often felt depressed after her son, Cai Jiayuan, was killed in the blasts.

5% of the chance

On Sept. 12, Liu Yun'ai went to Changsha city by herself to undergo IVF treatments at a hospital in Hunan province, central China. Her husband, Cai Laiyuan, stayed at home, making arrangements for their son's funeral.

Doctors at the hospital told her the success rate was barely 5 percent for women at her age. She was also informed that even many younger women, who have a success rate of 70 percent, can still fail to remain pregnant after spending more than 200,000 yuan ($30,400).

Liu asked for her husband’s opinion. He said: "If there's even a shred of hope, we will give it a try."

Baby named "success"

To get prepared for the baby, Liu stayed in Changsha for two months. She got up at 6 o’clock in the morning to go jogging. She also ate mud fish to obtain extra protein.

Finally, Liu became pregnant. On the 27th day of her pregnancy, she experienced bleeding, and the doctor could not detect the fetal heartbeat. Fortunately, this turned out to be a false alarm. She is now expecting to give birth at the end of June.

"He will be named Cai Jiacheng [cheng means success in Chinese], because finally we made it," she explained.
