The outer part is temporarily over

I have updated the external article of "Yang" with a certain length. There are still some differences between my self-feeling and the style of the text of "Yang". However, this is also what I wrote carefully. Originally, I wanted to write it as a time-travel article, but later I still adhered to the local main line.

Now "Refining Yang" is about to be put on the shelves, and the outer article will be temporarily updated here. If there is a chance in the future, I may write some more. Some readers still prefer the development of the outer article.
