Introduction to the ancient inn: Standing on the post road, facing the ancient post pavilion, it seems that you can still see the migrating businessmen coming and going, and you can still hear the "clack-tat" sound of horse hooves passing by on the ancient post road. . I once heard from old people that in its heyday, the Ma'ao Ancient Post Road served as a necessary place to cross Dinghai and an important transportation thoroughfare connecting important ferries. The old Sanjiang Wharf was a prosperous private commercial port at that time. At that time, there were 7 ships and 3 small boats going to Shengsi, Daishan, Xiushan and other islands every day. It was also a major commercial port leading to Ningbo, Shanghai and the mainland. When traders, tourists, officials, etc. disembark from Sanjiangkou, they must pass through the ancient post road to Dinghai. If they are unable to go forward due to wind and rain, they will stay at the nearby ancient inn. Today, there is still an ancient inn in Guangyi Village of Ma'ao, which was used by pedestrians and traders traveling on the ancient post road to wait for ships, rest and stay. Whenever merchant ships dock or go to festivals, inns, sedan shops and all kinds of fresh, salty and fish shops do a prosperous business. Snack markets were formed on both sides of the post road, and there was an endless stream of people coming and going. The night market business at that time was also extremely prosperous, and it was not inferior to today's night food stalls.
