On October 28, owners of the C&D Jiuliwan residential complex in Wuxi, Jiangsu, posted videos reporting serious quality issues such as roof cracking in stacked units, construction waste buried in the waterproof layer, and water accumulation under the insulation layer. They stated that despite daily rights defense efforts, the issues remain unresolved. Netizens mock the development as 'C&D Water Curtain Cave'.
