　　At 9 a.m. on September 19, 2026, a lovely ecological scene appeared in the waters of Qiansandao in Rizhao. A group of dolphins frolicked and swam on the sea surface, leaping out of the water and shuttling nimbly, presenting a spectacular view.

　　In recent years, Rizhao has continuously advanced marine ecological protection and restored the offshore marine environment, achieving steady improvement in seawater quality. As dolphins have high requirements for living environments, their clustered appearance in the Qiansandao waters vividly reflects the continuous improvement of local marine ecology and the steady recovery of marine biodiversity.
