Beijing, September 9 (Youth.cn) - On September 7, 2025, in Haining City, Zhejiang Province, driven by the erosion of tidal creek systems in the intertidal zone at the Qiantang River estuary, the mudflats have formed sprawling dendritic patterns known as “tidal trees”. These breathtaking formations stretch across the landscape like a grand oil painting, creating an awe-inspiring spectacle. Photo/CFP
