TAIPEI, Taiwan >> People across China reacted with relief and caution today to the dramatic government decision to loosen some of the world’s most severe COVID-19 restrictions.

For the first time in months, Jenny Jian hit the gym in the southern metropolis of Guangzhou without being required to scan the “health code” on her smartphone, part of a nationwide system that tracks where hundreds of millions of people go.

Elsewhere, virus tests no longer were required to enter many public places under changes announced Wednesday that followed nationwide protests against restrictions that have confined millions of families to their homes. Schools in areas without outbreaks were ordered to reopen.

“It was implemented very quickly,” said Jian, a 28-year-old resident of the southern city of Guangzhou. “But policy is one thing. The main thing is to see what the experience is when I step out the door.”

The changes are in line with the government’s promise to make restrictions less burdensome while still trying to contain the virus. While it’s not clear if the new rules are a direct response to the protests, they address some of the most pressing issues that drove people on the streets.

The state crackdown on the demonstrations was swift, if largely out of sight, and the flash of public anger faded from view even before the changes were announced. For now, it’s unclear whether more protests will flare given a quickly changing situation.

Among the most significant changes announced was that people who test positive for COVID-19 but show mild or no symptoms can now stay at home — a 180-degree turn from the previous policy, which sent all infected people to government field hospitals that became notorious for overcrowding and poor food and hygiene.

Chinese officials who spent three years warning the public about COVID-19’s dangers have also begun to talk about it as less threatening — a possible effort to prepare for living with the virus, as many other nations have done. Official messaging today particularly emphasized the point, with several state media outlets sharing a lengthy explainer that noted the virus is here to stay.

“The past three years have made us not want to come in contact with the virus … but actually in human society, there are thousands of microorganisms,” a team working for prominent government doctor Zhang Wenhong wrote. “Inadvertently, every year we will get sick briefly because we’ve been infected by several of these.”

Still, experts were careful to underscore this was not the end of COVID-19 containment.

“It is not that we are going to lie flat. Precision prevention must be still adhered to,” said Yu Changping, a doctor in the department of respiratory medicine at the People’s Hospital of Wuhan University. “The opening is an irreversible trend in the future because most people have been vaccinated and there has been a lower number of serious illnesses.”

While outside experts have increasingly criticized China’s containment policy as unsustainable, they have also warned that the country will now face a challenging first wave, as the loosened measures will no doubt fuel an increase of cases. That could be particularly difficult because many elderly people are not vaccinated and the country’s strict policies have meant few people have natural immunity against the virus.

“Every country in experiencing their first wave will face chaos, especially in medical capacity, and a squeeze on medical resources,” said Wang Pi-sheng, Taiwan’s head of COVID-19 response. Wang said Taiwanese living in China could come home for medical treatment, especially if they’re elderly or at high risk.

Bracing for the possibility of getting infected, people in the southwestern city of Chongqing rushed to buy cold and fever medicine, in line with government advice. In Beijing, some pharmacies ran out of the drugs.

Even the possibility of buying such medicine was remarkable, as the new rules relaxed restrictions on them. During the height of the pandemic, such over-the-counter medications could only be purchased through a lengthy application process and just visiting a pharmacy risked triggering the health code smartphone app.

But after three years of continually changing restrictions, many were cautious about rejoicing too early, wondering how the new measures would be carried out.

“All the policies are there, but when it gets to the local level, when it gets to the sub-district level, your neighborhood, it’s a complete mess,” said 65-year-old Yang Guangwei, a retiree who lives in Beijing.

The new measures also mandate fewer PCR tests, noting they must be targeted at those in high-risk industries and not entire districts. At the height of some lockdowns, many cities carried out daily tests. In recent months, Beijing and Shanghai residents had to take one every two or three days just to be able to move around the city.

One Beijing resident who gave only his family name, Qian, out of concern for discussing government policy, noted that testing is still required to access some places.

“They say don’t test, but the workplace still requires it. That’s contradictory,” Qian said of his own experience.

Underneath the official announcement of rollbacks posted on social media by state broadcaster CCTV, users expressed skepticism and noted that uncertainties abound.

One user asked if universities, many of which had prevented students from entering and leaving freely in the past few years, would return to normal. Others wondered whether certain cities would get rid of their quarantine-upon-arrival measures, as mandated in the national policies announced Wednesday.

But some expressed hope that the measures would open up new possibilities, like travel, which has been severely curtailed.
