我国古诗中有一种诗叫回文诗,它可以倒着读或反复回旋地阅读,多属文字游戏。回文诗难写,因为倒过来读时,诗的语法和诗歌的意义都会改变,而且往往变得面目全非。例如,“上海自来水”,倒过来读变成“水来自海上”。这就给做回文诗的诗人提出了难题,从诗的任何一头读起来,无论含义 In Chinese ancient poetry, there is a kind of poetry called palindrome. It can be read backwards or repeatedly and convolutedly. It is mostly a word game. The palindrome is difficult to write, because when reading it backwards, the grammar of the poem and the meaning of the poem will change, and it will often become unrecognizable. For example, “Shanghai tap water” reads “water from the sea” in reverse. This poses a problem for poets who make palindromes, reading them from any end of the poem, regardless of meaning.
