Tongzhou District, Beijing. The North Canal originated here. It emerged because of water and flourished due to grain transportation by water.

At the Beiguan Sluice, the starting point of the North Canal in the north end of the Beijing-Hangzhou Grand Canal, the magnificent Daguang Tower stands before us. It is not only a landmark building on the North Canal but also carries profound historical and cultural significance. 

With its elegant shape, the Daguang Tower served as the Grain Inspection Department of the Ministry of Revenue during the Ming and Qing Dynasties and was responsible for inspecting grains. The name "Daguang" originated from "The Book of Changes" and implies being upright and honest. It is a product and historical witness of the canal culture.
