Figure: Sun Nan was beaten seriously and has basically lost balance, needing someone to support him. Is this really the case? Of course not! The real situation is this: In fact, these pictures are all old ones, just no one paid attention to them before. This set of pictures was taken two years ago (2007) when Sun Nan, Jing Gangshan, Zhou Xiaou, A Duo, Zhang Yao, Xie Tianxiao, Gao Xiaosong and others gathered together. They were not holding a nostalgic concert, but rather filming a movie called "Pirate Cat".
