This work takes the science and technology on the canal as the first, and vividly demonstrates the profound wisdom contained in Chang'an Sluice in the form of following the drifting movements of the ships in it. As the boat drifted away and introduced into the clouds, the clouds spun and blended together and slowly moved away from both sides. The introduction of the "Grand Canal Trumpet" surfaced upward. After feeling the wonderful sunset scene of the canal that boatmen can enjoy every day, the sound of the Grand Canal trumpet will sound, and a small animation will show the scene of labor on the canal. The rise and fall of the sound and the long flow of culture are followed by the unique customs on the canal-the canal fishermen in Huai 'an, Jiangsu Province, "handing over the bow", "pre-flood banquet" and "full load meeting", followed by the introduction of the characteristic customs and intangible cultural heritage of the eight provinces in the order of the canal flow.
