Hmm,,, Basically most mining farm locates in sparsely-populated northern area, you know, cheaper electric charge and rent, I don't think there is any mining farm in ShangHai....
They're not that hospitality I geuss, especially letting you take a photo. If you want to do some stuff related to Bitcoin, go to HK. Chinese are focusing on stock market right now, many people dropped out from mining.
Thank you!
What about places friendly to bitcoin?
I plan to visit Shanghai, Guangzhou, Beijing, Hong Kong and some other cities.
