Dear PTS,
I think the oversea professionals chose Hangzhou because it is a place more easily reached and known by forereigners, a city of better "political protection", better public facilities (internet, hotels etc), less "air polution" than Shanghai apart from suitability of solar observations. Tongling is not so in these aspects. As for weather, Hangzhou and Tongling are so close geographically, their weather conditions should not make much differencene. If they see the eclipse in Hanghou, part of it is really luck.
