This is just a picture of an empty office, I don't see anything that connects this particular empty office to any particular entity. You might as well claim this office belongs to Avalon, Bitfury, or Huwaei. It's like people selling miners without their username/date--it's not very strong proof of anything.
Any thoughts?
Yes, it's asicminer office (room 1317). I can gurantee, I've been there. Before the holiday, there were many young guys working there.
And you know what? The ShenZhen office of TSMC is downstairs (room 1201) !!!
Are you sure?

Looking at the Chinese in the photo (yes, I read Chinese). Office 1317 does *not* seems to be ASICMiner. It says something like "Shenzhen XXXX XXXX Investment Consultancy Company Ltd" (XXX XXX is too blurry to see) and "Hong Kong XXX XXX International Group".
If you insists they are ASICMiner, it may be ASICMiner is hiding under these company names, or something else.
