Introduction to Duoyunxuan: In the 26th year of Guangxu (1900 AD), a new paper fan shop was opened on Henan Road, one of the cultural streets in Shanghai. This was the famous art garden in Jiangnan in the future - Duoyunxuan. The 1990s were a time of great change for Duoyunxuan. Relying on the brand advantage, it successively established Yunxuan Art Auction Company, Duoyunxuan Antiques Co., Ltd. and Duoyunxuan Brokerage Co., Ltd. Now it is famous for its business in Chinese calligraphy and painting and the related Four Treasures of the Study. Its woodblock watermark reproduction art stands out from the north and south of Beijing's Rongbaozhai.
