You can't do that.The transaction on the hbg is a black box for external observers. When transferring the same currency on the hbg, the transaction will not be recorded on the orignal blockchain. They just record the transfer internally, which can save a fee.
You actually can for the most part (onchain transactions). There are a couple services out there which group wallet adresses from popular exchanges.
https://www.walletexplorer.com for example does this. I really doubt it is 100% accurate, but it should give you a good indication of the number of HUOBI adresses.
