On September 16, multiple BYD Changfeng-affiliated 4S dealerships in Guiyang, Guizhou (including Changfeng Wangchao, Qianxindi Haiyang, etc.) were exposed as having closed overnight. Employees were owed months of back pay, and suppliers and staff staged rights defense actions on-site; numerous car owners are facing dilemmas such as being unable to register their vehicles, hindered delivery, and unfulfilled after-sales service packages.
