Wang Chao's blog

One night I burned all my memories, and then my dream became transparent. One morning I threw away all yesterday, and then my steps became light.

Why build this independent blog

  • Experience summary, learning note taking, problem analysis and solution process recording.
  • Sort out ideas, sort out logic, improve document writing ability and language expression ability.
  • Share and harvest happiness. With the help of other blog articles, I hope my notes can help others.
  • To deepen the understanding of technical knowledge, even if you have seen other people’s analysis, you need to understand it yourself and express it in language.
  • To build a personal brand, everyone has their own brand. Whether it’s job hunting or making friends, the original blog is a good personal card.
  • Make like- minded industry friends, exchange and learn from each other.
  • Pure function, strong customizability, no advertising, content audit and so on.
  • Typesetting is simple. It is written in markdown language. Writing is typesetting. You can focus more on the content itself.
  • Articles may not be updated frequently, but each one is carefully written.
  • Remind yourself not to forget the original intention. When you don’t want to write a blog, look at this article again, hoping to remember the significance of opening this blog.
