Introduction to Huangshi: The most eye-catching thing about Diaoyutai is the strange boulder standing on the bank of Fayu River - "Huangshi". Huangshi is a huge and complete quartz granite body, with a large top and a small bottom, in the shape of a bowl. There are almost no cracks on the stone surface. On the north side of the Huangshi, there are four vigorous large characters of 1 meter square written by Xu Wenbo, the magistrate of Baoji County, in March of the 59th year of Emperor Qianlong's reign in the Qing Dynasty: "Yi Pu". The stone is 6.6 meters high, with an upper diameter of 11.2 meters and a lower diameter of only 4 meters. The rapids of the Fayu River rub against the stone, and it is likely to collapse if touched. However, for thousands of years, it has always been "steady as Mount Tai". .
