Sorry for poor English.
First, the Mudfish China server always out of service. Even it work, i got packet loss and disconnection of the game. I live in Hong Kong I try to use Advanced Mode/Multi Path Mode, it doesnt change.
Then, i try HK, SG, TW, JP, KR server, some times it okay, but more times is packet loss and disconnection.
If you want to connect to china game server, I’m not sure that there’s a good internet line with mudfish nodes because we’re not focusing to deploy mudfish nodes at around china at this moment because it’s very strict and limited. 
Not sure that FAQ - Nodes link is helpful but please check.
