In the past, it was not only the temple for Shennong--King of Medicine, but also an important medicine market and a meeting place for doctors. After the renovation, the hall now covers an area of about 1,600 square meters, and it has a large number of cultural relics of sculptures. Today, the hall is a pharmacy of Ningbo Dahongying Medicine Company, and at the same time, it is an exhibition hall of medicine history of Ningbo.
