Many years ago, I thought I was dead, but I woke up here...
(I have no intention of abandoning this article, but... The structure is too huge and I can't control it. I thought that later on, I overturned the original structure in order to solve the logical problem, and I was very entangled... I got stuck. As expected, I should just write the article without thinking about it first, and I can't start revising it without writing a few words... In fact, this paragraph... Was written for the only children's shoes collection. Thank you~~~)
