A group of children suffering from congenital heart disease are heading to Beijing for a life-change surgery. From last year, the Chinese government has started to provide free treatment to the sick children. With the programme going on, more and more of them are in good hope of living like other healthy children.

Yang Jen and her mother arrived at Lhasa railway station in good time. It's the first time these children have ever travelled by train, and they are full of curiosity.

Yang Jen, Tibetan child suffering from heart disease, said, "The trash can? Its here, put the trash into trash can."

The Qinghai-Tibet Railway runs from Lhasa to Beijing, a journey of over 4000 kilometers, much of it at an altitude of 4000 meters. In order to ensure that the children have a safe trip, two special doctors from Beijing will accompany them all the way along with some nurses. But the train had only run a short distance when one of children suddenly fainted.

Cheng Hongxia, a nurse, said, "The train has only just set-off, and their blood-oxygen level is at 73. Usually, when a normal person gets to TangGuLa Mountain Range they start feeling uncomfortable at 73, but we are just beginning our journey."

Zhang Lu, cardiologist in General Hospital of Chinese People's Police Force, said, "For him, the biggest problem is the lack of oxygen. If possible, can we hook-up some oxygen from a next station?"

One day passed, and the scenery outside the window goes from the wilderness to skyscrapers. The child who fainted has recovered and is once again able to play with others. As the train approaches Beijing, Yang Jen changes into her brand-new set of red Tibetan clothes. Yang Jen and the rest of the children all arrived safely, ready for their important surgery in the capital.

This time, 18 children have received the treatment. Later in the year, the programme will reach deeper in Tibet to the rural areas, and more children will have a better chance of living in health.
