This live guitar version of Edelweiss has stayed with 22-year-old Ye over the past weeks. It's what drew him back to conciousness.

"We thought this might be helpful, so I play the song for him, and it worked out well. He started to sing along." said Li Zhou, a doctor at Zhujiang hospital, Southern Medical University.

Ye began to have trouble walking at the end of last year. As his condition worsened, he was sent to hospital. There doctors spotted a huge tumor in his brain. Surgery was immediately arranged. The operation was a success, but two weeks after the procedure, the patient was still having a difficult time.

"If one's thalamus were damaged, the patient will suffer from symptoms such as fever, unconsciousness, and problems with his hydration and electrolyte levels." said Huang Qijin, Ye's chief doctor at Zhujiang hospital, Southern Medical University.

His relatives were full of anxiety. But a conversation between Ye's aunt and his mother caught the attention of his doctors.

"His mom said Ye always loved singing English songs, ever since he was young. He also learned some guitar and violin." said Mrs. Fang, Ye's aunt.

One of the doctors, Li Zhou, brought a guitar to Ye's room, and there, a miracle began to unfold. "After the surgery, his eyes were blank. They couldn't move or focus on people. But when he heard the guitar, we saw his face relax and his eyes lit up." said Li Zhou, a doctor at Zhujiang hospital, Southern Medical University.

The doctor says the thalamus is a key part of the human brain. It relays sensory signals to the cerebral cortex. Doctor Li has been playing Ye the same song every day. And with every set, more improvements have come. Some say music can take one back in time. For Ye, it is the love and care within, that brought him back to life.
