I'm going to be very sad to say that there is no update today, because the updated content is all gone. While waiting for the starting point background to open, I sent the written content to the USB flash drive for backup, completely forgetting that I opened it directly today and wrote it in the USB flash drive. So the end result was that I overwrote the new version on the USB stick with the old version on the computer. I want to cry without tears, and there is no more crippled hand than me. Is there a computer expert to help you answer, can there be a way to revert to the previous version in this situation? I really don't want to rewrite it~~\
