Introduction to the Royal Wharf: The Royal Wharf is a symbol of Huai'an's status as an important transportation hub for "Southern Ships and Northern Horses" during the Ming and Qing Dynasties. It was built in the sixth year of Yongzheng in the Qing Dynasty (1728). The steps of the wharf are made of stone, so it is also known as Mingshi Pier. Ships going south can disembark here. In the Qing Dynasty, Shikuan Street was densely populated with mule and horse stalls, restaurants and guesthouses, and there were so many merchants that it was so prosperous that it was known as "Nine Provinces Connected". Emperors Kangxi and Qianlong visited the south of the Yangtze River six times, and visited here many times to inspect water conservancy and observe the people's sentiments. The stone wharf site was listed as one of the top ten historical and cultural monuments in Huai'an City in 2007. A stone monument was built near the wharf that reads "Southern Ship and North Horse Boat Landing".
