The people of the Eastern Sea... are very abnormal!
This is the conclusion King of Qin arrived at after years of observation and extensive review of historical records.
The Eastern Sea has a substantial population. Although not as vast as the North's hundreds of billions, its numbers rival Jiangnan, with over ten billion people scattered across its expansive coastal areas. There are large and small fishing villages, and some even reside on islands closer to the mainland.
But upon close inspection, the situation with the people in this region is exceptionally strange.
Eastern Sea's marine trade is flourishing, connecting the rivers of the Central Plains effortlessly. Its proximity to both Yundu and the Capital City's Main Cloud River makes it an ideal hub for maritime commerce. Yet, the locals resolutely avoid engaging in business, handing over profits to ship merchants from other places.
