thank you

but the input transaction from huobi exchange with standart fee
How can I make double spend from huobi??

huobi should know better then to do something like this. You should contact them to see if they can double spend one of the inputs and credit your account back the ~9 BTC. Once they do that you can withdraw from your huobi account again.

Most reputable exchanges will not spend any customer deposits until it has (at least) one confirmation to avoid something like this from happening. The unconfirmed transaction is most likely a customer of their's mining revenue.
