It comes from British Prime Minister William Pitt. The original text is like this: "The poorest people dare to resist the authority of the king in their own huts. The house may be dilapidated and the roof may be crumbling; The wind can blow into this house, and the rain can enter this house, but the king can't step into this house, and his hordes dare not cross the threshold of this broken house. "

German emperor William I once built a palace in Potsdam. On one occasion, William I climbed a mountain to overlook the panoramic view of Potsdam, and found a shabby little mill standing beside the magnificent palace, which was really "unsightly". William I thought he was a Democrat, so he first sent someone to negotiate with the miller and buy the mill for demolition. Unexpectedly, the miller is a stubborn old man, and he is determined not to sell it, because it was left by his ancestors and he can't beat it himself! In a rage, the king sent guards to forcibly dismantle it, but the miller did not give in and filed a lawsuit with the German court. The German court accepted the case and ruled that the king lost the case according to law, demanding that the king rebuild the mill according to its original appearance and compensate the miller for his losses.

Later, William I and the miller both died. The small miller wants to go to town to sell the mill. He couldn't help thinking of his old buyer, and he didn't know whether the second generation was interested in the mill, so he wrote a letter to William II. William II wrote back to him and said, "My dear neighbor, you have read your letter. As a neighbor, I am deeply sympathetic to know that you are short of money now. You said you would sell the factory, but I can't put it off for a while. After all, this mill has become a symbol of German judicial independence. It should be preserved in the name of your family for generations. As for your financial difficulties, I will send someone to send three thousand marks. Please be sure to accept it. If you are embarrassed to accept it, even if I lend it to you, it will solve your temporary emergency. Your neighbor William II ".

After many rulers, today, as a symbol of judicial independence in Germany, the mill represents a nation's belief in the law and stands on the land of Germany like a monument.
