On October 21, 2024, a sudden surge in tidal waters at Zui Dong Pier in Luan Nan County, Tangshan City, Hebei Province, caused flooding in multiple residential homes and courtyards during the early morning hours. On-site footage revealed water levels rising above ankle height inside some affected homes. In Nanbao Village, several courtyards were also inundated, prompting residents to erect wooden planks at their doorways in an attempt to block the incoming tide.

Staff from the Luan Nan County People's Government stated that this tidal surge was the largest in decades. At around 4 a.m., personnel from the town government and emergency management bureau swiftly arrived at the scene to initiate rescue operations. Currently, the economic losses caused by the tidal surge are being tallied and verified. Relevant departments will spare no effort to ensure the safety and livelihood of residents.
