The Leifeng Pagoda, also known as the Imperial Concubine Pagoda and the Xiguan Brick Pagoda, is located on the Leifeng of the sunset mountain on the south bank of the West Lake. The Leifeng Pagoda was first built in 977. It was built by Qian Hongchu, the loyal king of Wu and Yue, in order to worship the Buddha's hair relics. Since the completion of the tower coincided with the passing away of Qian Hongchu, the posthumous posthumous posthumous scholar of the Northern Song Dynasty, Sun's wife was named "Imperial Concubine", so it was named "Imperial Concubine Tower". Later, because the mountain where it is located is called "Lei Feng", it is gradually called "Lei Feng Pagoda".
