To visit Dongguan First, then Shangai, Foshan city, sun light ind.zone, anji country.advise distance

I advise you to go to Foshan from Guangdong first, because there are many buses from Dongguan to Foshan.
After that, you can go back to Guangzhou to take flight to Shanghai. The trains and the buses will take you about 24 hours to reach Shanghai, so the flights are the best choice.
From Shanghai to the Anji County, you need to take the bus from the Shanghai South Bus Station.
As for the Sunlight Industry Zone, I cannot figure our where it is, so I cannot tell you how to get there.
