Sorry for answering in English because we're not offering technical support with other languages. Frankly speaking I can't understand your question.  :-(  Could you please explain your issue in English?  If then I can help you little bit more.

Unfortunately the game server in China is not officially supported by Mudfish yet. As workaround you should use one of methods at Unsupported Games. And if you want to see it officially at Mudfish, please send me some game packets using Packet Capture with Mudfish link while playing the game with Full VPN mode. I need some game packets to register new game.
