This book is not going to be written.

Here's why:

One. Seeing too few people.

Two. Self-reality reasons.

Three. I feel that I am not enough, and I plan to dive in and study hard

Four....... Hee-hee.

In the end, if someone is watching, we're sorry, but if there's no one, then think it's me comforting myself.
