In sensitive areas, historical factors often exacerbate the emotions of local residents, including the following aspects: 1. **Colonial history**: Many areas have experienced foreign colonial rule, and this history often leads to local residents' antipathy and resistance to foreign forces. 2. **War and conflict**: Historical events such as wars, conflicts or genocide may leave deep trauma in the hearts of residents, leading to hostility or distrust of certain groups. 3. **Economic deprivation**: Historical resource deprivation caused by wars, policies or external interventions may cause poverty and dissatisfaction among local residents, exacerbating emotional intensification. 4. **Cultural and religious differences**: Different cultural and religious backgrounds may have caused conflicts in history, and the related painful memories may exist in society for a long time, affecting current social interactions. 5. **National identity and historical narrative**: The interpretation of past events in historical education and narratives will affect people's national identity and strengthen the victim consciousness or superiority of certain groups. 6. **Political manipulation**: Certain political forces may use historical events to incite national emotions in order to achieve their political goals. This kind of manipulative propaganda often exacerbates social contradictions. 7. **Immigration and exile**: Historical immigration or refugee issues may trigger local residents’ rejection of “outsiders” and affect social stability. In these sensitive areas, historical memories are often reinterpreted and used to arouse emotions, so understanding and dealing with these historical factors is an important part of promoting reconciliation and stability.
