Chang has his own way of looking at his transformation: "Of course you've got to be able to think critically, but if you can't raise up people's character from the base, your criticism, no matter how brilliant, will simply serve as window dressing and won't accomplish anything. Why not promote Falun Gong instead, which has much faster results!"
對此，張清溪自有看法：「批判精神當然要有，但如果不從根本上提振人的心性，再怎麼猛烈的批判也只是打在棉花上，毫無效果，還不如推廣法輪功，收效更快呢！」
