The autumn basin river brought prosperous trade economy to Hui'an in that year, because the trade in that year was operated by small boats, so the autumn basin River also had its very excellent use. Later, with the growth of trade and the emergence of big boats, the autumn basin river was no longer able to carry the trade development of Hui'an. Moreover, the siltation in the river made the river no longer able to walk big boats, so it slowly withdrew from the prosperous trade stage in history.
