In 2008, Peng attended the Beijing Olympics, a contestant in a sport that drew little attention and in which there were no national resources (only subsidies, airfare and lodging in the Olympic Village courtesy of the Chinese Martial Arts Association of ROC). His Wushu performance won him the silver, causing a great sensation in mainland China.
2008 年，在體育界既不重視也不看好、也沒有國家資源（僅有武術協會補助機票及入駐選手村）的情況下，彭偉群在北京奧運賽技壓群雄，摘下武術表演賽的銀牌，轟動大陸。
