The world is bustling for profit. Rivers and lakes don't believe in tears, life doesn't sympathize with the weak, and the world is prosperous, all for profit. Living in this world, everyone's life is hard to avoid, and everyone's heart is hard to avoid some distress and confusion. It can even be said that suffering and hardship are life itself, which is innate and can't even be cancelled for life. Otherwise, life is not very simple. The key is to see if you are a strong man in life and overcome it.
