The Beijing Hangzhou Grand Canal was built in the spring and Autumn period. It is the longest and largest ancient canal in the world. The canal has played a great role in the economic and cultural development and exchanges between the north and South regions of China, especially in the industrial and agricultural economic development of the regions along the canal. But now its functions are forgotten, and its derived culture is ignored. I can't bear to see the intangible cultural heritage in front of my home so neglected. So there's this exhibition design. By calling on people to collect and unlock maps, we can understand the collection and stories of the canal, so as to understand the canal knowledge and culture.
