The Great Firewall Report (GFW Report) highlights how the central Chinese province of Henan has adopted its own provincial firewall which is less sophisticated and robust than the central government’s but more volatile and aggressive, blocking significantly more websites than the national-level censorship system.
Local sources told Radio Free Asia that the heightened restrictions at the provincial government level may reflect uncertainty about instructions from higher authorities, leading to “excessive blocking” to avoid blame for failing to carry out their duties.
GFW Report is a censorship monitoring platform, primarily focused on China. During one experiment its researchers ran between Dec. 26, 2023 and March 31, 2025, they found that the Henan Firewall blocked 4.2 million domains, about six times that of the 741,542 at the national level.
Since 2023, netizens in Henan had reported a rise in the number of websites that were inaccessible in the region but accessible elsewhere in China, the study found.
“This localized censorship suggests a departure from China’s centralized censorship apparatus, enabling local authorities to exert a greater degree of control within their respective regions,” researchers Mingshi Wu at GFW, Ali Zohaib and Amir Houmansadr at University of Massachusetts Amherst, Zakir Durumeric at Stanford University, and Eric Wustrow at the University of Colorado Boulder wrote in the GFW Report published in May, “A Wall Behind A Wall: Emerging Regional Censorship in China.”
But the phenomenon extends beyond Henan, sources inside China told RFA.
Local governments in neighboring Hebei, another central Chinese province, as well as those in Tibet and Xinjiang have been operating similar censorship systems as the one reported in Henan for at least four years, Zhao Yuan, a network engineer based in Hebei, said.
