Rumors online claim that from July 2025, Li Keqiang's wife Cheng Hong and their daughter issued an open letter demanding an investigation into the cause of Li Keqiang's death; from the end of 2025 they sought the intervention of party elders such as Wen Jiabao and Wang Yang; in January 2026 they reportedly said that if the investigation was not reopened they would go to the petition center to file a public petition, with Wang Yang, Liu Yuan and Hu Chunhua said to be on their side.
