In 2005, as a second-year graduate student in sports education at TPEC, Peng won two silvers and a bronze at the East Asian Games, and at the World Wushu Championships he won the silver in Nanquan and the gold in Nandao while competing against contestants from more than 80 countries. Taiwan's representative teams hadn't won so many titles in years, and Peng began to climb his way upward in international Wushu circles.
2005 年，已是北體運動教育研究所碩二生的他，在東亞運贏得二銀一銅；當年武錦賽則在八十多個參賽國中，拿下南拳銀牌、南刀摘冠，締造台灣睽違多年的佳績，從此在國際武壇竄起。
