Preface

I wrote 10 chapters in the previous chapters that were not effective, so I deleted them and started again.

Writing is a passionate thing, but passionate cannot be supported for too long

So we need everyone's support, more people will give you feedback and return at 1 o'clock

Everyone tells me what is bad about the article in my heart, so I can correct it. I also hope that everyone can always express their thoughts and add some characteristics to my article
