From 2013 to 2019:

Photos Before and After

These photos were taken on December 25th 2013 (Before our Geobiology Clearing Ceremony for Beijing). You could not see the mountains in the background.

Then on Dec. 26th (after the Geo Ceremony), now with mountains. Then 3 photos of 2 days after the Geo Ceremony, where the sky is getting bluer and clearer.
