Beijing is reimposing restrictions in many parts of the city in response to a new cluster off covert cases.

As other countries emerged from months of lock down the new outbreak, there is a reminder of how difficult the road to recovery could be, and questions are still being asked about China's early handling off the outbreak.

The first case of Covert 19 was in the city of Wuhan, probably at the beginning off December last year.

In total, there were nearly 4000 deaths and over 50,000 infections on our China.

Correspondent John said with has just returned from a visit to Wuhan, he said.

This report for two months time stood still in this city.

Has it endured one of the world's harshest lockdowns?

Now it seems a distant memory interrupted lives have resumed again.

But beneath the appearance of normality, the authorities are on edge people.

We arranged to meet our followed by plain clothes.

Police who block our car white white were stopped from filming a human female allotted up knotted up.

We can't leave.

And at this apartment block, a group of officials keeps a careful eye on us.

We've been detained during the lock down.

Anger erupted here over how it was managed, with a national vice minister heckled on an official visit.

It's all fake!

They shout.

Maybe it was a sign of how the crisis shook the foundations of a system one now firmly back in control.

No interviews, she's told.

People may say something they don't mean, this, official says, explaining his concern about our filming.

In January.

Wuhan's health service was the first to experience the onslaught, but despite evidence the disease was spreading, the public was given little warning.

Doctors were silenced by the police, and one of them, Liwen Liang, later died.

But a small shrine on offering is made to a dead brother.

Mas Wong, who doesn't want to use her full name, has been told by the police not to talk to the foreign media but has chosen to ignore that warning.

44 year old Wong Fei died in early February in the same hospital as Dr Lee Wen liang.

They should have warned the public in time, his sister tells me.

If they hadn't covered it up, my brother might be alive now.

Anyone asking similar questions to publicly is quickly silenced got to love for China.

There is now only one narrative that matters in Wuhan.

The undoubted success in eventually bringing the virus under control.

China is determined that this place will not be remembered for a cover up that put global health at risk, but rather as the cornerstone of a great national victory, one that demonstrates not the weaknesses of tight political control but its strengths in Wuhan's night market, businesses still slow but by the crayfish stalls.

There's only patriotism and praise.

Chinese people united to control the epidemic, this man tells me.

But you foreigners don't know how to protect yourselves.

Yeah, it's gonna stop it.

Here's another difference outside one of the hospitals and nurse we've just interviewed is intercepted by the police and questioned putting a regular.

Of course, if it brings you trouble, we won't use your interview.

She calls, is later and asks us to delete the interview.

It is harder to fight a virus in the face of public criticism and democratic debate, but without them, might China miss the signs of the next public health crisis, too.

On tomorrow night's program, most scientists think the virus came from bats via an animal in a market than to humans, but will also visit the labs from which the US claims the virus was leaked, John said Worth BBC News.
