Old illnesses are hard to treat

Dear readers,

The first time my younger brother wrote a book, he updated it wherever he thought of writing it from the beginning to the present, and he didn't make a draft, so there were a lot of mistakes in the previous article......

Furthermore, the names of the characters of this theme should be changed, I didn't pay attention to it at first, and now I have begun to make up for it, but the affairs are cumbersome, and it may have an impact on some aspects, so please forgive me......
