Recently I witnessed a commotion in downtown Guiyang where there were a lot of honking horns and police were standing at attention, saluting.  There was a traffic procession. It turns out that the doctors from Guiyang who went to Wuhan to fight the virus were returning home after about one month on duty. They were being given an honorable welcome home from the local people.
