There is a saying in Beijing: "The palace house, the jade wall and the silver of Su Zhi are all measured." Legend has it that in those days, because there was too much silver, Sue had to bask in it every year, for fear that it would become moldy. Su Wang sat leisurely in his room drinking tea and said to the housekeeper, "Go and check and see if there is any money." The housekeeper went out a little and reported, "No less". Su Wang nodded: "Sun is coming again." The next day, King Su said to the housekeeper, "Go and see if you have any money." The housekeeper went out a little more and reported, "No more, no less." Su Wang nodded again: "Sun is coming again." After several times, the housekeeper realized that she was in charge, and everyone took a dustpan of silver and took it home. Turning around, she reported, "There is less money." Su Wang nodded: "Then put it away."
Gongwangfu is located in Shichahai area, a treasure trove of geomantic omen in Beijing, covering an area of more than 60,000 square meters. Known as "ninety-nine and a half rooms", the back building divides it into a mansion and a garden. The mansion is grand and solemn, and the garden is beautiful and prosperous. In the front and back seas surrounded by Wang Fu and Baylor Mansion, Gongwangfu is called "the best landscape in the city" because of its richness, and it is even more famous because it is comparable to the official residence system of the Forbidden City.
