Yeah, I have to agree I tried looking up demographic information about Chongqing and Chengdu and while they do seem to be growing, I didn't see anything that could explain a growth of that magnitude. Maybe it's an artifact of some interpolation method he's using? The source data he linked to seems only to go to 2000, so I'm not sure where the data for 2005 - 2015 came from.

The 2005, 2010, and 2015 numbers are projections based on data from 2000:

I should add a note about the Chongqing spike being incorrect to the about.
