In the Tang dynasty (619-907), the poet Du Fu wrote a famous poem Thoughts on Staying Again at Wuhu. A famous stone tablet in Wuhu recording local events of the Song dynasty period (ca. 1000 AD) is considered to be a masterpiece of the renowned calligrapher Mi Fu. Folklore An itinerant blacksmith named Tang Tianchi is reputed to have invented the wrought-iron picture in Wuhu, when a painter whom he admired chided him, "You will never make pictures by beating iron." Another blacksmith of the Spring and Autumn period (770-476 BC) named Gan Jiang was famous for sword making. Zhe Shan (Reddish Brown Hill) is said to get its colour from the flames of Gan Jiang's furnace. Sheng Shan (Sacred Hill) is the legendary location of his sword grinding rock and tempering pool.
