The Beijing-Hangzhou Grand Canal is the earliest and longest man-made canal in the world. With a total distance of more than 1700 kilometers, it starts from Beijing and ends in Hangzhou. The Grand Canal plays a great role in the exchange of economy and culture between southern and northern China, especially in the industrial and agricultural development in the canal line area.

Wantou town is an ancient town along the Grand Canal in Yangzhou, East China’s Jiangsu province, with a history of 2,500 years. Recently, it has been transformed into "the hometown of Chinese jade carving". Nearly a thousand jade merchants gathered in the town, creating a flourishing jade industry.
