On Sep 18, Liu Anjun, a family member of Sun Meihua, disclosed that the Xicheng police in Beijing demanded that the family disband online chat groups and prohibited any public mention of the matter, while also banning audio and video recording during meetings. Previously, Sun Meihua was brought back to Beijing on Sep 8, but family visits were obstructed, leading to demands for confirmation of her health status and a thorough investigation into the circumstances of her disappearance.
