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.
