"My performance in the Olympics was perfect, but also a great pity. When I saw teammates hanging the Chinese national flag in the highest place and singing the national anthem, my heart was really aching...I have dreamed of this moment countless times...You guys say yes to the performance I have had in the Olympics so far. But I still think there is one thing left uncompleted...and I have no chance to finish anymore...This is also a lifelong regret. A deepest pain in my heartGoodbye, London!"
