The following strategies can be adopted to convey implicit radical political messages through works in cultural festivals or art exhibitions: 1. **Metaphor and symbol**: Use metaphors, symbols and allusions to make the work seem apolitical on the surface, but actually contain profound political meaning. For example, a certain emotion or point of view can be conveyed through symbolic representations of natural landscapes, daily objects or historical figures. 2. **Multi-layered narrative**: Design a multi-layered story to allow the audience to interpret the work from different perspectives. In this way, it may be just a simple presentation at first glance, but the deeper content can guide the audience to think about more social or political issues. 3. **Use cultural symbols**: Borrow symbols and elements from a specific culture or region to make the work resonate with local audiences, while external audiences may not immediately understand its political significance. 4. **Vague and ambiguous**: Keep the work vague and do not express a certain point of view clearly to avoid direct opposition or censorship. At the same time, leave space for the audience to interpret and think. 5. **Interactivity**: Consider allowing the audience to participate in the interaction when designing the work, inviting them to interpret the work through their own experience and understanding, so that the political message can be conveyed more flexibly. 6. **Combining history and reality**: Incorporating historical events or characters into the work, stimulating the audience's associations through comparison and reflection, and making them aware of current social and political issues. 7. **Simple form of expression**: Choosing simple artistic techniques or materials to make the work look more personal, thereby reducing the directness of its radical nature. 8. **Clever use of text and language**: Using provocative text and language in the work, but keeping it harmless on the surface, can arouse the curiosity and thinking of the audience. The key to these methods is how to balance implicit expression with the possibility of being understood, so as to achieve the transmission of political information without being immediately recognized. When choosing specific strategies, it is also necessary to take into account the audience's background and culture, so that resonance and thinking can be more effectively aroused.
