I received this one today and want to teach my child how to use it in Chinese. The specific model is the 2.8-inch H version. I saw a video on B站 (Baidu Video) by Chengdu M哥, where he was teaching people how to use MS, but the device wouldn't automatically restart and just showed a blank screen. I need to start using it in the next few days, so I'm looking for some help online.😥

Guys, this is urgent! I'm really worried about spending 300 on something I haven't even tried yet.😥
