MVC-based cross-cultural communication platform to assist the construction of VR environment for smart training of Chinese as a foreign language is studied in the paper. The interactive interface and interactive content of virtual elements need a specific carrier to realize. Specifically, the interactive information recognition and reception are realized by the head mounted virtual equipment, and the information interaction between the real environment and the virtual environment and between the user and the system is realized by combining the interactive functions realized by the interactive interface. The synchronous output of feedback information is also realized while the control information input is completed. The virtual scene modeling needs to be based on the real scene, combined with that according to the actual environmental requirements, hence, we then apply to the smart training of Chinese as a foreign language as the testing scenario. Through the experimental analysis, the performance is tested.
