The utopia in Cheng's mind doesn't necessarily involve revolution and overthrow of the social system; it could also be an individual's pure wish for making life better-- for instance, finding a place where one can have a life and settle down or a state of mind free from worries and distractions.
鄭文堂心目中的「烏托邦」，不一定是社會體制的變革，也可以是個人單純地想讓生活更美好的想望，譬如說，一個安身立命的所在、一份無須憂慮焦躁的心境。
