Some notes taken as a part of trying to decide where to go for the total solar eclipse on July 22.  The total eclipse starts at 09:04 in Deqin and progressively later in cities further east.  Sunrise (calculated based on Shangri-La) should be around 06:40.

The NASA GIS maps (Shangri-La/Zhongdian, Xichang, Litang, Leshan, Chengdu, Chongqing, Yichang, Wuhan, Shanghai, Hangzhou, Suzhou) seem to agree with Jay Anderson's maps (Shangri-La/Zhongdian, Litang, Shangri-La/Zhongdian, Litang, Leshan, Chengdu, Leshan, Chengdu, Chongqing Yichang, Wuhan, Shanghai, Hangzhou, Suzhou) and both disagree with this interactive map of the eclipse path.  I tend to trust the eclipse expert and the NASA, but the interactive map is good for exploring options.

The NASA site has a lot of good maps and pointers

Location	Duration of Totality	Chance of Cloudiness
Litang	3 minutes	55% chance broken clouds, 28% chance overcast or obscured
Leshan	4 minutes 30 seconds	32% chance broken clouds, 52% chance overcast or obscured
Zhongdian	2 minutes (interactive map says 0)
Xiangcheng	4 minutes 30 seconds (guesstimate)
