But if the cuckoo singing in spring is a "good thing," one cannot help wondering why it should be associated with such a melancholy legend, instead of being greeted as ushering in the new season like the plum blossom and the oriole. This may have something to do with the cuckoo's real-life natural history.
但仍讓人不免想問的是，杜鵑既是「好東西」，孟春啼叫，卻不似「梅花開頭先含笑，黃鶯接著唱新調」具有踏春氣息，反與怨鳥傳說相連，又是為何？
