SHANGHAI:A Chinese court handed a four-year jail term on Monday to a citizen-journalist who reported from the central city of Wuhan at the peak of last year's coronavirus outbreak, on grounds of "picking quarrels and provoking trouble," her lawyer said.

Zhang Zhan, 37, the first such person known to have been tried, was among a handful of people whose firsthand accounts from crowded hospitals and empty streets painted a more dire picture of the pandemic epicentre than the official narrative.

"We will probably appeal," the lawyer, Ren Quanniu, told Reuters, adding that the trial at a court in Pudong, a district of China's business hub of Shanghai, ended at 12.30 p.m., with Zhang being sentenced to four years.

"Ms Zhang believes she is being persecuted for exercising her freedom of speech," he had said before the trial.

Criticism of China's early handling of the crisis has been censored, and whistle-blowers, such as doctors, warned. State media have credited success in reining in the virus to the leadership of President Xi Jinping.

The virus has spread worldwide to infect more than 80 million people and kill over 1.76 million, paralysing air travel as nations threw up barriers against it that have disrupted industries and livelihoods.

In Shanghai, police enforced tight security outside the court where the trial opened seven months after Zhang's detention, although some supporters were undeterred.

A man in a wheelchair, who told Reuters he came from the central province of Henan to demonstrate support for Zhang as a fellow Christian, wrote her name on a poster before police arrived to escort him away.

Foreign journalists were denied entry to the court "due to the epidemic", court security officials said.

A former lawyer, Zhang arrived in Wuhan on Feb. 1 from her home in Shanghai.

Her short video clips uploaded to YouTube consist of interviews with residents, commentary and footage of a crematorium, train stations, hospitals and the Wuhan Institute of Virology.

Detained in mid-May, she went on a hunger strike in late June, court documents seen by Reuters say. Her lawyers told the court that police strapped her hands and force-fed her with a tube. By December, she was suffering headaches, giddiness, stomach ache, low blood pressure and a throat infection.

Requests to the court to release Zhang on bail before the trial and livestream the trial went ignored, her lawyer said.

Other citizen-journalists who had disappeared without explanation included Fang Bin, Chen Qiushi and Li Zehua.

While there has been no news of Fang, Li re-emerged in a YouTube video in April to say he was forcibly quarantined, while Chen, although released, is under surveillance and has not spoken publicly, a friend has said.
