Only by sharing can knowledge be spread, new knowledge can be promoted, and more can be learned. Every text/blog written here is basically queried from the Internet I took a look at the information and recorded it. Some of it was moved over as it was, and sometimes I added some of my own ideas. I hope it can help everyone.
