It is typographical stuff like space between two languages and between word and digit. Indeed the tutorials are excellent, but the space style does not follow a consistent writing style, like https://github.com/eunomia-bpf/bpf-developer-tutorial/blob/main/src/0-introduce/README.md
Describe the solution you'd like
Either no space between English and Chinese and no space between word and digit, or one space between English and Chinese and one space between word and digit, in one tutorial docs. One file should has one style and keep it everywhere.
