As the world's leading athletes compete for medals in Rio, a special sports event was also held in the city of Toronto, Canada. More than 200 athletes from different parts of Canada took part in the Canadian Transplant Games last week -- an event mainly aimed at athletes who have received organ donations or have donated themselves. Lu Wei has more.

Competitors come from different age groups, ranging from four years old to over 80 years old. For them, it is not only a sports event, but also a celebration of new life.

Chad, one of the athletes in the Games, donated his liver and kidney to his two kids. "I gave my kidney and my liver to each of my kids. My son here Felix received my liver, he is 10 years old now, and my daughter who is 3, received my kidney." "I feel ok. I ran 5 kilometers two days ago."

His son, Felix has joined two sporting events. The long jump and sprinting event. "He is like a normal kid now, he can run and play and jump," said Chad.

Zheng Qiling, a Chinese-Canadian volunteer, has been dedicated to calling on organ donations. As a donor, who donated one kidney to her mother in 2008, she began to ride across Canada in May to tell her story along the journey.

"I was very fortunate to be able to come here as a volunteer. The same day after I donated my kidney, we need more people to become living donors," Zheng said.

The president of the Canadian Transplant Association, David Smith also received a kidney from his brother. He said the purpose of the Canadian Transplant Games is to demonstrate the physical success of organ donations and transplant surgeries, and raise awareness of the need to increase donors.

President of Canadian transplant association, David Smith, said, "As we have in Rio, the Olympic Games are going on and we set up our own games, very similar to the Olympics, where everybody chants behind athletes and beyond."

The World Transplant Games has been staging international sporting events for transplant athletes since 1978. Currently, athletes of the World Transplant Games come from 51 countries and regions, including China.
