In 2021，the concept of the Metaverse has become a hot topic in various fields with the Facebook renaming to Meta，As the integration of various technologies，the Metaverse has great application potential in the field of intangible cultural heritage（ICH）inheritance and safeguarding. According to whether there is interaction in the application，the application forms of the ICH Metaverse can be divided into digital reproduction and virtual presence. The digital reproduction can be divided into reduced dimension projection and multi-dimensional simulation according to whether the information is complete. The reduced dimension simulation is the main application form of ICH Metaverse at this stage，which also reflects that the ICH Metaverse is still in the primary stage of development. And there still remains risks and challenges in the process of the ICH Metaverse construction，such as the lack of systematic planning，immature technology，high application threshold，lack of representative applications，vigilance against capital kidnapping and the deepening of theoretical innovation.
