You maybe right, it may be ASICMiner is hiding under these company names or they just didn't replace the old company name.
I also checked out the mail box of 1317 and the name is 深圳比特泉信息科技有限公司 that is Bitquan or Asicminer.
深圳
比特泉信息科技有限公司
Found that:
比特 (bǐtè) =
bit (binary digit) (loanword)
泉 (quán) = spring (small stream) / mouth of a spring /
coin (archaic)
