Is there a free trial?
I’d set a trial credit now for your account. 
So I think you can use all mudfish nodes and features for a while. Please let me know if there’s any problems and questions.
Hi, thank you very much for the trial credit. How do I use the features? I tried to equip but can’t do anything…? Also, I am based in Beijing at the moment, do I need to use VPN to use Mudfish…?
For most of cases, I don’t think you need to use other VPNs. Please confirm that How to check the basic functionality works fine in your environment. It’s a first thing you should test.
