It is said that the economic zone planned by the Heixinggen conglomerate in the Far East, encompassing Lunan, Northern Su, Yudong, and Northern Anhui, is an economic depression, which is actually a result of the combination of natural and man-made disasters over the years.
Man-made disasters certainly play a major role. After all, since the Yellow River changed its course in the Song Dynasty, its estuary has always been in Northern Su, and the flood impact has persisted. However, relying on the Grand Canal, this area has always been one of the most economically prosperous regions from the Ming to the Qing Dynasty.
In the early Qing Dynasty, like all unified dynasties, it had the ability to manage the Yellow River. Now, choosing to let it deteriorate, combined with the rise of maritime transport, led to inevitable decline.
