I watched the NKF charity show just now. There are some performers like Liang Zhiqiang who claimed that he had never tried his stunt on metal fans and that night was his first. There are so many first time that made me wonder are they really telling the truth? I don't think it is possible to perform without practice especially in front of national tv. C'mon guys, tell the truth! I ain't 3 years old kid to fool.
