The link is to SCMP video of events described by the FT this way:
A strict lockdown of [Hubei] province ended on Wednesday, but many of its 6m residents who work in other parts of China are finding it impossible to leave as other local authorities defy central government orders and refuse to lift travel restrictions.
On Friday that opposition erupted into violence as thousands of Hubei migrant workers tried to cross over a bridge linking Huangmei in Hubei to Jiujiang in neighbouring Jiangxi province. Video footage posted online showed police officers from Jiujiang and Huangmei wrestling with each other and hundreds of people attacking police and overturning their vehicles.
Hours after the incident took place, police from Jiujiang and Huangmei issued statements online, which were deleted shortly afterwards, accusing each other of causing trouble.
This happened on March 28 and I missed it at the time. It strikes me that China’s first major recession since its market reforms might be poised to expose serious fissures in the country. Here is one analysis of the government’s response:
This incident may not be the last of its type to emerge as a result of the pandemic, and the CCP has taken active steps over the past two months to reinforce political indoctrination for local police agencies—thereby attempting to ensure that police officers will remain loyal to the ruling party in the event of any major incidents that might threaten “social order and stability” (社会治安稳定, shehui zhi’an wending) in the country.
