"Go your own way and let others talk!" This sentence is a famous saying in his masterpiece "Divine Comedy". At that time, he tried his best to break through the shackles of medieval theocracy, and there was a very vivid description in his book. He even sent the Pope to hell and suffered the most cruel torture, which was contrary to that era and could not be understood and supported by people at that time, so he made this remark. But for us now, with the global village narrowing the distance between us, it seems that it is no longer feasible to completely ignore others. Those who have the opportunity and access had better ask others more. After all, what we know in the world is still very limited. The so-called threesome, there must be my teacher!
