Zhang Yu has been wondering recently whether he has picked the wrong string, and it has been wrong for twenty years. Or, it is not the wrong string, or he is mentally disabled, has a brain twitch, has a schizophrenia, has a split personality, is possessed, has Parkinson's disease, or he is dreaming of butterflies and can't wake up.
Either the things we encountered together were clear to others, but we were confused; what we saw, they couldn't see.
