Metauniverse is a virtual world that integrates all kinds of high-tech achievements. It is a concept put forward by Mr. Qian Xuesen and named as "spiritual realm". Metauniverse is not a brand-new technology, but integrates a large number of existing technologies, including 5G, cloud computing, artificial intelligence, virtual reality (VR), augmented reality (AR), blockchain, digital currency, Internet of Things and human-computer interaction. In the meta-universe, users can interact through digital identities, and experience a sense of reality similar to or even beyond the real world. This virtual world is not only a game field, but also a new social system, covering entertainment, socialization, education, work and trading.
