There were many public opinion polls in modern China, but the results were mostly released in the form of news reports, and official polling reports were rare. In terms of the percentage, only less than 10% of public opinion surveys resulted in survey reports, and the number of scientific and standardized survey reports was even smaller. In terms of content, most of the recent polling reports were about politics and diplomacy, but not much about other dimensions. On a technical level, with a few exceptions, the public opinion polls in modern China were relatively “naive,” due to most of these investigators who were lack of professional training in sociology, psychology and statistics, and lack of communication with foreign counterparts as well. Despite that, the public opinion polls in modern China have been “digitized” to show the psychological condition of the people in the face of domestic trouble and foreign invasion. This provides a different information resource from textual narrative historical documents for a dynamic understanding of the socio‐psychological basis of political, diplomatic, and economic and social changes in different stages of modern China’s history, and is of great intellectual and academic research value.
