The workplace is cruel and sometimes even dark. If you want to survive and develop in it, you must deeply understand its rules of the game. Rules are a system, unspoken rules are a game. Those who abide by the system can only be led by others. Only those who understand the rules of the game can live freely and even lead others. The workplace is an interpretation of life, so whether you are a newbie in the workplace or a senior manager; whether you are a white-collar worker in a foreign company or a leader of a state-owned enterprise, you are the protagonist of this period of life in the workplace. Some rules are better to know than not to know, because this is life. We cannot take risks and test all the hidden rules. What we want to achieve is rapid growth. By reading other people's stories, combined with your own experience and re-observation, you can make the invisible rules of the game clear; then, fight, struggle and succeed skillfully. This is the gift this book intends to give to all working people.
