作者注:本文原发表于台湾《铁路邮刊》第17期,引起了海内外一些邮人和谜友的兴趣,但美中不足的是其中有几条谜面被印错了字,造成不通不顺,深为遗憾。现转载时已作了更正,对个别谜面也做了较小的改动。 Author’s Note: This article was originally published in Taiwan’s Railway Journal Issue 17 and has aroused the interest of some postmen and riddlers at home and abroad. However, the fly in the ointment is that some of the mysteries are misprinted, Deeply regretful. At the time of reprinting, some corrections have been made and minor changes have been made to individual riddles.
