🎉🚀🌈 Here are my study notes 🍺🍎🎁

🙏 The purpose of writing notes is to assist my memory. Many things have wasted a lot of time just by memory and repeated search, so I organize these things into something like a log to record, so as to facilitate my rapid retrieval and location, rather than repeating them over and over again. Of course, I must have a lot of mistakes in understanding and recording. If you are accidentally misled, I apologize. Please forgive me for not deliberately.
