Under the wave of "information revolution", the impact on history is more thorough and revolutionary than any other era in the past. It is an irreversible trend for computational history to absorb the essence of information technology and show strong computing power. Where will historical research go? On the basis of concept discrimination, historical review and current situation analysis, the article concludes that: Chinese computational historiography has lasted for a hundred years since Liang Qichao initiated it. During this period, it has experienced at least several academic practices and schools such as statistical history, metrological history, information history, digital history, etc.. At present, the achievements of computational history focus on three aspects, including data integration and database, corpus and knowledge base construction and mining and analysis of historical text, visualization and GIS historical geographic information system. It should be noted that the so-called "prosperity" of computational historiography has a "foam" component. The superiority of "computing" technology is easy to forget its "double-edged sword" side, the weakening of human nature and humanistic spirit is also worrying. Only by constantly reshaping its own scientificity in the process of crossing, breaking through and self awakening, computational historiography can show its trend and future in the major of "grand history", learning of "overall history" and discourse of "Chinese history".
