Notes
1. If you don't have a specific prototype, don't bring in too many real people.
2. Common sense is bound to have errors, so popular science is welcome.
3. The main line is emotion, and the writing is just a joy.
Purpose: In competitive life, you are destined to leave the field lonely, but the competitive spirit will always shine.
