Introduction to the Suihuang Mausoleum: Located 1.5 kilometers southwest of the ancient city of Shangqiu, it is about 10 meters high. It is the tomb of Suiren, the ancestor of fire, one of the three emperors who brought light to the Chinese nation and was the first to start artificial fire. Because Suiren is one of the legendary "Three Emperors", it is called Suihuang Mausoleum. The mausoleum of Emperor Sui is tall and large, covering an area of more than 40,000 square meters. The 5,000-meter-long wall and wall tiles are antique, and the mausoleum gate has three couplets, which is very spectacular.
