The evil CCP has no time to control the Internet recently. Because of the economic collapse. A stock trading market is BiG Shit market and Hong Kong stock trading are both 0, which has collapsed. Both American and Japanese companies have moved out of China, leading to the danger of China's economy. CCP has no money to maintain the firewall.
Doesn't take much money to add a domain to a blocklist WUMao's might not know much about nostr yet. They will though.
China's economy has collapsed 😡. 500 million Chinese are unemployed, with no benefits and no subsidies, so China is the most dangerous country. Sooner or later, there will be a problem.
500 million people are unemployed, which is quite horrible. The CCP relies on violence to maintain stability, and the Chinese are cowardly and incompetent. There's no trouble.
500,000,000 人？我不相信。
