November 30th should be of great significance in China's three-year history of epidemic prevention. Because the two cities announced the lifting of the lockdown at the same time on this day, it basically put an end to the end of this round of epidemic and also set a final example for the future epidemic prevention model.
Zhengzhou announced on November 28 that it would lift the temporary control of eight districts and surrounding counties in the city on November 30, and cancel the nucleic acid in low-risk communities on the last day. Before this, Zhengzhou announced that the five surrounding counties will have three days of temporary control from November 23, and from November 25, it will also announced that the eight districts in the city will implement control.
Later, Zhengzhou adjusted its policy, allowing the surrounding five counties and eight districts in the city to be unblocked simultaneously. The nucleic acid that was originally planned to be temporarily cancelled for several consecutive days was also temporarily cancelled due to some special reason. By November 30, Zhengzhou fulfilled its promise and all controls in the city except for high-risk buildings were lifted.
On the afternoon of November 30, several districts in Guangzhou announced the lifting of temporary control, including Haizhu District , which was the most severe epidemic. At 4 pm, water horses on the roadside at the boundary of the temporary control area of multiple sections of were demolished, and private cars, trucks and pedestrians came out one after another.


The unblocking of the two cities, one south and one north, is essentially different from the previous unblocking of the city, and is also very different from Shijiazhuang half a month ago. The current epidemic situation in the two cities is still at a high level. Zhengzhou has nearly 1,000 new cases in a single day, while Guangzhou has nearly 8,000 new cases in a single day.
Although there are many differences between the two cities in the scale of the epidemic, urban population and local economy, the two cities have relatively close measures to unlock the lockdown, such as 48 hours of nucleic acid cross-regional and outing, and business and dine-in will be resumed as soon as possible. The whitelist system is still implemented for enterprises to resume work and production, and offline teaching has not been restored.
This can be regarded as the real dynamic zeroing , which is different from the previous requirement that unblocking must achieve social zeroing. In fact, it is almost impossible for the two cities to achieve complete social zeroing. It can only be guaranteed that the social situation will be cleared at the moment of unblocking. In the past, the social situation generally required that the social situation be cleared for three consecutive days, and the incubation period can only be fully unblocked after the incubation period.

Our epidemic has spread to a wide range and a great impact than ever before. The ending of such a result means that the epidemic prevention policy has been adjusted or compromised according to the development of the epidemic, and our epidemic prevention situation will become more complicated in the future.
is neither a full liberalization nor a one-size-fits-all approach, which puts higher requirements on city managers. In fact, after Guangzhou and Zhengzhou were lifted, the epidemic is now relatively serious. Cities with a long-term outbreak, such as Chongqing, will inevitably follow up in a short period of time.
Other cities with short-term epidemics, such as Beijing, Tianjin and other cities, will no longer carry out regional control. This means that large-scale blockade will become history. Especially in first- and second-tier cities, epidemic prevention has become a normalized process. For residents, the biggest possibility is that control based on buildings may arrive at any time, with a short period of time but a high frequency.

From the results, we are no longer able and patient for a city to completely eliminate the epidemic. With the outbreak of the epidemic periodically, our future epidemic prevention policies are likely to change from dynamic zeroing to preventing large-scale outbreaks.
Shijiazhuang's previous unblocking control can be understood as the policy callback to , and the final result will inevitably be the same as that of Zhengzhou and Guangzhou. Unblocking to a limited extent and relaxing in an orderly manner, rather than a one-size-fits-all manner.
Around the Spring Festival, we will face huge challenges. If we can spend this year's Spring Festival smoothly and ensure that the epidemic does not change significantly, then the practices of the two cities will definitely become a sample of epidemic prevention for a long time in the future.
