Intro:

China's Olympic medal hope Liu Xiang's shock exit from the London Games has caused some of his compatriots to call for the 110m hurdle star to quit.

Script:

SOUNDBITE (Mandarin): Du Xing, Olympic spectator, Chinese national who works in London
"I was the only Chinese spectator in the starting line seats, so I was the only person cheering for him before the race and I felt very lonely. When he fell and stood up again, the spectators, including the British spectators, in the whole venue applauded him. I was very touched."

SOUNDBITE (Mandarin): Dong Lina, Olympic spectator from China
"I feel really sorry for him because we all had great hopes for him and wished he could race to a good result. But he fell on the first hurdle and our hearts also fell."

SOUNDBITE (Mandarin): Du Xing, Olympic spectator
"My feelings are very complicated. Liu Xiang raced in the London Diamond League and he seemed in good form. It's a real pity that he didn't finish the race this time. I think it's time for him to quit."
