COVID-19 Timeline from inside China

Based on my detailed daily Facebook updates and notes from within China during the entire COVID-19 outbreak, until the end of March, I have assembled an easier to read chronological COVID-19 Timeline of major events that I had previously reported.  This COVID-19 Timeline, in conjunction with my daily statistics, may provide researchers, historians (and nutty conspiracy naysayers) a better outline of reality (or not, depending on what some wish to believe).

NOTE: The first column after the date with tick marks indicate those events I personally experienced, the 2nd column, those I saw reported in major media, typically, in multiple sources. 

The timeline in chronological order:

Dec 19 The Wuhan Center for Disease Control and Prevention (CDC) in central China’s Hubei Province detected cases of pneumonia of unknown cause.
Around Dec 21 Through diplomatic backchannels, China gives heads up to the diplomatic community (at least the USA, UK, Canada, Europe and Australia) about a mysterious pneumonia virus in Wuhan. 🇺🇳
Dec 24 Close friends, a Consul General and his wife of a major country gave us a heads-up at a Christmas eve party of this troubling mysterious pneumonia virus.
Based on experience from SARS (and common sense) I go into self-imposed isolation as a result of the seriousness of the warning.
Dec 30 The Wuhan Municipal Health Commission issued an urgent notification to medical institutions under its jurisdiction, ordering efforts to appropriately treat patients with pneumonia of unknown cause.
Wuhan CDC issued emergency warnings to local hospitals about a number of mysterious pneumonia cases discovered in the city in the previous week
The National Health Commission (NHC) make arrangements to send a working group to Wuhan to conduct on-site investigations.
Dec 31 The Wuhan Municipal Health Commission released a briefing on its website about the pneumonia in the city, telling the public not to go to enclosed public places or gather. It suggested wearing face masks when going out.
Chinese state television CCTV channel 13 in their daily news broadcasts reported about the unknown virus, adding that a team of experts from the National Health Commission would arrive in Wuhan.
The World Health Organization (WHO) detects reports of a cluster of cases of pneumonia of unknown cause on the Wuhan Municipal Health Commission website.
