This is an essay that I have inspired to write from time to time. It is both colored and weird. Anyway, I write it when I think about it, and post it when I write it. However, it is not suitable for posting ultra-short Ah here, so I did not update it at the same time. I have collected 100 articles and posted them together. Maybe I have posted some of them before. Anyway, this time it is all. Friends who are interested can watch the Happy Wave Number
