There is a book on sunflower in the Jianghu, and everyone wants it. Because it can be invincible after getting it, but if one day, the sunflower collection is made public, everyone will have a chance to practice. Is this a good thing or a bad thing?
This will be a disaster. Because a person has it, it is a person's business to practice or not. Everyone has it. It's up to you to practice or not. For example, if you have an enemy and you don't practice, the enemy will kill you after practicing, so you should practice.
Finally, everyone in the Jianghu will practice the sunflower collection. Practicing classics can be invincible, but because everyone practices and everyone is invincible, there is no invincible, and if you want to practice magic, you must first enter the palace. So Jianghu people became eunuchs. This is a lose-lose result, and no one benefits from their extra efforts.
Similarly, the current training institution is an open sunflower collection. If you don't study, other children will do better than you. If you want to learn, you may lose your childhood in the palace. If everyone is studying, but the number of places to go to college has not changed, no one will benefit from it, and all participants will lose their childhood.
This is the involution.
Every era has its problems. It takes generations to change your life. Reading is the best way to break the circle.
