At the children's department of the Citizen's Hospital.

A couple was extremely anxious, "Doctor, what should we do now?"

The main doctor shook his head, "There's nothing you can do. I suggest that you go to Shanghai or Beijing Children's Hospital. We can't treat this disease here."

The couple looked extremely helpless. Their child was five years old. He had been feeling weak every day since a month ago. He slept for almost twenty hours every day and he still felt weak when he woke up. He didn't have the liveliness of a child. As his parents, they didn't notice it for the first few days as they thought that their child might have been too exhausted from playing. However, they realized that there was something wrong.
