Beginning in the late evening of the 5th and continuing until the early morning of the 6th, Nanjing police carried out a highly secretive and significant operation. They conducted surprise inspections of three relatively well-known entertainment venues. Due to allegations of involvement in illegal sexual activities, the Nanjing Avoiding Wind Harbour Sauna Co., Ltd. on Hanzhong Road in Gulou District, the Nanjing Mingshang Polygold Nightclub on Rehe Road in Xiaguan District, and the Nanjing Red Cube Entertainment Co., Ltd. on Wangfu Street in Baixia District were all ordered to cease operations for rectification. Eleven people were placed under criminal detention, and eighteen others received public security penalties. Relevant individuals from the Nanjing police stated that this operation was part of a broader summer campaign to comprehensively address public security issues.
