In this day and age, if you don't watch the news for a week, you will find a big change. The development of the times is accelerating, and perhaps one day suddenly we will all become a useless class. Morning jog this morning...... Passing by the labor market, the early morning is full of people, most of whom are elderly...... Life is not easy, and you can earn 100-200 a day when you get up early and are greedy for darkness. The world is meant to be like a game...... Sometimes people don't understand the rules of the game and get tired and tired. But it's not possible for everyone to understand the rules...... If the total amount of the world is viewed as a whole, then the people participating in it are equivalent to a zero-sum game.
