China was reunified under the Sui Dynasty (581–618). Under this short-lived dynasty, many reforms were initiated that led to the subsequent success of the Tang dynasty. The only coin associated with the Sui is a Wu Zhu coin. Additional mints were set up in various prefectures, typically with five furnaces each. Cash was frequently checked for quality by the officials. However, after 605, private coining again caused a deterioration of the coinage.
