Introduction to the Ancient Canal: The Yangzhou section of the Ancient Canal is the oldest section of the entire Jinghang Grand Canal. The current canal in Yangzhou is mostly consistent with the ancient Hangou route more than 2,000 years ago. It is completely consistent with the canal dug by Emperor Yang of the Sui Dynasty. It is 125 kilometers long from Guazhou to Baoying. Among them, the Yangzhou city section of the ancient canal is about 30 kilometers long from Guazhou to Wantou, forming the famous "Yangzhou Three Bays". This section of the canal is the oldest, with numerous historical sites and cultural landscapes.
