You can choose to read books, books from the table of contents are very organized, reading books can be systematically learned, step by step, no matter how good or bad your foundation is, find a systematic book to read from beginning to end, you must insist, you can install a Linux virtual machine in the early stage, repeat the practice as the main means, and eat a book well.
