MiHoYo is a Chinese video game company that was founded in 2012 by three college friends, and it is the developer and publisher of the popular game Genshin Impact. As far as I am aware, MiHoYo has not changed its name, and it is still officially known as “Shanghai MiHoYo Information Technology Co., Ltd.”
However, in some cases, companies may change their name as part of a rebranding effort or to reflect a change in their focus or mission. Without more specific information about the context of your question, it is difficult to provide a more detailed answer. If you can provide more details or context, I would be happy to try and provide a more helpful response.
