On Jan 3, he was summoned by Wuhan police for "spreading fake information on the internet". He was reprimanded but not fined or detained. The doctor died on Feb 7.

Xu, from the Jingsh Law Firm, said: "What Li Wenliang said online was not totally wrong. It was based on his own studies. There was no conclusion at the time as to whether Li's comments were fake or not, and his warning to others was based on his occupation."

Under Chinese law, rumors are defined as falsified information or that without basis in fact.

Xu said more time and studies are needed to prove whether comments or conclusions, especially those involving science and technology, are true. He added that it was improper for law enforcement departments to draw blind conclusions.

"We should have no tolerance for and oppose those who intentionally forge and post fake information to disturb public order. We must also be clear that any information has been forged before taking action," he added.

Xu said those found to have spread rumors face administrative detention ranging from five to 10 days as well as a fine. He said they should also be held criminally liable if their behavior has a significant negative effect on society.
