Silk Expo Introduction: Qingzhou was an important intersection between the Silk Road and the Maritime Silk Road in ancient times. There was a prosperous silk trading market in Qingzhou during the Ming and Qing Dynasties. This building from the Qing Dynasty was once the famous "Guangtong Hengda Silk Shop" at that time. Now it is engaged in the silk business and is also the Silk Expo in the ancient city of Qingzhou, becoming a microcosm of Qingzhou's once prosperous silk trade.
