Abstract: Collective memory affects people's behavior choices and plays an important role in people's selection of tourism destinations. The human memory, natural memory, and social memory possessed by the tourist site itself and the collective memory obtained through family, school, media, society, and beliefs together constitute the pull and the push that influence people's decision-making in the process of tourism destination selection. Tiananmen's flag raising ceremony has become a tourist attraction for tourists because of its unique form and its special space and time.
