In New Culture movement, Liang Qichao reconstructed Confucianism and Confucian history. He carried on the thought of counter-metaphysics in late ming dynasty, interpreted renewedly the thought of Dai Zhen, Yan Li and Wang Yangming, and tried to advance a new Neo-confucianism, which returned to primitive confucian. I try to reveal the intention of Liang Qichao's study of confucian, which is to transform traditional confucian into modern "philosophy of life". Moreover, his project of chinese modern academic development was different from the movement of "zhengli guogu" (整理國故) started by Hushi.
