Tiana choked on a piece of plastic while playing at home on April 9 last year when I was doing housework.

Her heart had stopped, so my husband and I took her to a hospital. Five minutes later, doctors were able to restart her heart, but she had to be place dona ventilator because it was very hard for her to breathe. When she was transferred to Beijing Children's Hospital, she was in very bad condition.

In the following days, we prayed for Tiana, but she was not getting any better and remained unconscious.
