In the current era of reconstructing cultural memory through digital media, new forces in Chinese animated films, represented by "Ne Zha 2" (hereinafter referred to as "Ne Zha 2"), are shining brightly. The evolution and rebirth of the Nezha character in animation from the 1979 film "Nezha Roars in the Sea" to contemporary times reflects the innovation of traditional cultural communication methods in the era of media convergence. Currently, animated films, with their inherent advantages in comprehensive artistic forms, have broken through the temporal and spatial barriers of traditional cultural dissemination. When the bronze artifacts from Sanxingdui, which had been dormant for thousands of years, woke up on the screen of Nezha 2, the bronze patterns transformed into the shining skin of boundary beasts, and the archaeological code was revealed as breathing civilization messengers. Hardworking animators use animation effects to revive silent cultural relics in light and shadow. Behind the rebirth of ancient artifacts, does it reflect museum archaeology? The collision of media with the movie screen. This is not just a simple reproduction of cultural relics, but a spark that reignites Chinese civilization through high-tech digital audio-visual technology. Although social short videos have formed the advantage of cultural dissemination through algorithmic push, their fragmented nature makes it difficult to carry the complete storyline. Games can interact with users, but their task oriented mechanisms often undermine the integrity of cultural connotations. In contrast, the animated film "Chang'an 30000 Miles" uses light and shadow as ink, turning Li Bai's poetry into touchable landscapes - the audience follows Gao Shi on horseback for three hours, from the bronze bells on the eaves of the Yellow Crane Tower to the banners on the snowy plains outside the Great Wall, the atmosphere of the prosperous Tang Dynasty slowly unfolds in the field of screen consumption. The cultural identity brought about by this deep immersion goes beyond the linear reading of picture books and the real-time interaction of mobile live streaming, forming intriguing and lasting cultural memories. Surprisingly, overseas movie audiences also enjoy 'Ne Zha 2'! Sichuan Opera's gongs and drums collide with Hollywood style editing rhythms, unleashing brilliant sparks of cross-cultural resonance, allowing overseas audiences to understand Eastern aesthetics in the vivid animation frenzy without the need for subtitles. Animated movies transform local cultural elements into cases that are acceptable to young people worldwide, and the digital reconstruction of Sanxingdui cultural relics is a typical practice of this cultural transformation. Light and shadow have no borders, and the audio-visual recombination of animation transcends the barriers of epic translation. It's like a bronze divine tree stretching in the clouds in a movie, and digital special effects give traditional culture a sense of the times, allowing global audiences to understand Chinese symbols through visual impact. The current technological innovation in animated films is reshaping the way traditional culture is disseminated. The digital reconstruction of the mythical buildings at Chentangguan in Nezha 2 using virtual production technology not only restores the architectural form of the Tang Dynasty, but also reproduces the beauty of the "morning bell and evening drum" through dynamic light and shadow changes. This cultural presentation goes beyond the two-dimensional expression of painting and is also different from VR technology - reproducing traditional charm from multiple angles in the interplay of reality and virtuality. Digital technology is not a deconstruction of traditional culture, but a new type of memory device. How to maintain cultural integrity in the traffic logic of social word-of-mouth and algorithm recommendation? How to maintain the purity of cultural genes in the practice of cross media adaptation industry? Animated films in the era of short videos have their own way of survival - building a dynamic balance between technological empowerment and cultural consciousness. When short video recommendations constantly cut the audience's attention, we can try to combine modular story units with immersive experiences, which not only adapt to the dissemination rules of short video platforms, but also preserve the complete storyline in the structure of long films. In cross media adaptation, a digital cultural gene database can be established to preserve vector data of traditional patterns through 3D modeling. By using blockchain technology to issue an "electronic ID card" to each cultural symbol, blue and white porcelain patterns can maintain their genetic purity during secondary creation and gain new life through algorithm recommendations.? This not only allows traditional culture to ride the fast train of technology, but also preserves the soul spark of artistic creation?. Animated movies are like the rebirth of traditional culture in the digital tide. This transformation is not simply a transfer of media culture, but a way of reconstructing the encoding of cultural DNA through digital technology. After Nezha 2, animated films will continue to play the role of pioneers in the modern transformation of Eastern culture in the foreseeable future. (New Society)
