"Red Story Yuanuniverse" is an advanced red ideological and political immersive experience project based on Unity engine. It aims to accurately restore and reproduce historical scenes through digital means and combine immersive interactive technology to enable users to experience, tell and create red culture in an all-round and multi-angle way. In the carefully constructed VR scene, users can play the role of the Red Army and experience the hardships of climbing snow-capped mountains and grasslands, thus deeply understanding the bravery and greatness of the Red Army's Long March. In addition, users can also share the red culture in the virtual forum, interact with peers in real time, and jointly explore the connotation and value of the red spirit.
