On September 23, Cai Xiaodan updated her rights-defense progress on Bilibili, saying that it had been the fifth day she stayed overnight in the company's conference room awaiting a reply; her 83-year-old grandfather felt unwell and was taken to hospital by ambulance 120, and after receiving an IV drip he returned to the company to fetch belongings but was blocked again. Her husband passed away nearly nine months ago, and the company has repeatedly called the police to demand that the family members leave.
On September 17, Cai Xiaodan, widow of engineer Zhang Liang, and her family were invited to negotiate with Beijing Fanghong Intelligent Technology Co., Ltd., a subsidiary of Tsinghua Tongfang. The company promised twice to provide a written response by the end of the workday on September 21, but as of September 23, it has failed to do so, nor has it provided the requested materials such as work records, attendance sheets, and payroll records.
