简介：After noon, there is no wind today, and the early winter sun shines warmly on the Bohai Sea. Because of the protection of the Bohai Bay, the Bohai Sea is almost an inland sea. The sea breeze is gentle, the walrus has always been relatively stable, and there are few strong winds and waves. As far as ship navigation is concerned, the Bohai Sea can be said to be the safest sea area around the Ming Dynasty.
