Italy generally believes that the earliest bank was established in Venice in 1580. Later, the Netherlands set up banks in Amsterdam, Germany in Hamburg and Britain in London. From the end of18th century to the beginning of19th century, banks have developed generally. Banks originated in the Tang Dynasty in China. During the Xuanzong period of the Tang Dynasty (847-858 AD), there was a "gold and silver shop" in Suzhou. In the second year of Jiayou in the Northern Song Dynasty (1057), when Cai Xiang knew Fuzhou, he wrote sixteen things to teach the people, the sixth of which was "Qianzhuang boasted more money", which was the earliest time when the word "Qianzhuang" appeared alone.
