Zhang's thought is influenced by many factors, and its changing process is quite complicated. According to his self-report in Han Wei Yan, it is summed up in four words: "At first, customs come true; at last, truth turns to customs". Generally speaking, it can be divided into 1908 (Guangxu twenty-four years) and On the Interpretation of Everything. Prior to this, Zhang studied Pu Xue, hundred schools of thought, western evolutionism and sociology. After being jailed for reporting, he was changed to Faxiangzong. Later, he thought that the knowledge of pre-Qin philosophers was not comparable, which could be described as "turning vulgarity into reality". Since the publication of Shuo Wen Jie Zi, Zhang Taiyan, inspired by the thought of everything, no longer only takes knowledge as the sole criterion, but instead thinks that all the knowledge of "benefiting from the outside and solving the worries from the inside" is valuable, and begins to re-evaluate the academic thoughts at all times and at all times. That is, to enter the realm of "returning to nature and getting rid of vulgarity".
Zhang Taiyan's ideological background mainly comes from four aspects: first, influenced by the textual research of Ganjia, he emphasized objective demonstration; Secondly, following the rising trend of philosophers in the late Qing Dynasty, we respected the thoughts of Xunzi, Zhuangzi and Laozi and Confucius. Thirdly, influenced by Yan Fu, in his early articles, he especially took evolution as a theoretical framework; Fourthly, Buddhism, especially the epistemology in Buddhism, is the pillar of Zhang's later thought, which makes his ideological system full of individualism and relativism. In addition to these four origins, the national thoughts of Gu and Wang Fuzhi, as well as the thoughts of Zhang Xuecheng, Dai Zhen, Sun Yirang and Kang Youwei also had a considerable influence on Zhang Taiyan.
