Rewrite the Technological Landscape

I went back to my hometown these two days, because I haven't been back to my hometown for a long time, and I have dealt with a lot of things more busy than expected. I really didn’t save the manuscript. I have been busy for a day and now I just got home. When you encounter such things as leave, I implore you to forgive me. I will try to stop asking for leave in the future. I am sorry again, and I wish you all a happy new year...
