北执南矣
[bĕi zhí nán yĭ]
The meaning of this net name is rather profound. The north (represented as cold) adheres while the south (symbolizing warm) has already gone, which symbolizes clinging to things that should pass, or being caught in the irreconcilable conflict between letting go and hanging on. Meanwhile, some Chinese idiom says: A stubborn person always goes opposite way, just like someone comes from south but chooses the north way firmly without hesitation, it means a fool does wrong things firmly.
