Qing Dynasty
The Zaolutang (Duckweed dew hall) Medicine Shop was founded in 1623 at what is now the Wuwei crossroad of Xi' an. It was famous for a formula for treating women's disorders. This signboard was written by Zhang Yude, a famous Shaanxi calligrapher, in the 18th century. (Collection of Zaolutang Medicine Shop, Xi'an, Shanxi Province.)
