As the saying goes, "Advice when least heeded is helpful to action", a wise gentleman needs someone around him to correct his mistakes, so that he and his regime can go further. So there must be many ministers around him.

Debate is a courtier who dares to speak out and advise. There are many courtiers in history, such as Wei Zheng and Di Renjie, whom we are familiar with. The reason why these people became relegated ministers is inseparable from the wise monarch they followed. For example, Wei Zhi often remonstrated with Emperor Taizong, which made him angry several times. Nevertheless, it is obvious that Emperor Taizong can listen to Wei Zhi, and it is precisely because Emperor Taizong reused courtiers such as Wei Zhi that he opened the way for the rule of Zhen Guan in the Tang Dynasty. Emperor Taizong of the Ming Dynasty and other emperors understood that although what these courtiers said was ugly, they really started from themselves, the court and the people all over the world. If you don't listen to their opinions, it is likely to go against the sky and be very dangerous.

Being in power is the same as studying. If you don't advance, you will retreat. If a leader is not good at listening to the opinions of his subordinates, then he and his team are not far from failure, so there will be many courtiers around Mingjun who dare to speak out.
