勾手指尾的起源及意義

１）為什麼人總是要以勾手指尾作為承諾的象徵？
從前，
有一個公主，
她到了結婚的年齡。
她挑選了五位王子作為最後夫婿的候選人，
她把手放在背後，
要五位王子猜想她舉著那隻手指。

第一位王子選了拇指，
那當然是錯；
第二位王子舉了食指，
當然也是錯；
第三位王子舉了中指，
換來公主的一巴掌；
第四位王子舉了無名指，
當然也錯了；
最後，
第五位王子舉起了尾指，
公主把自己的手伸出來，
和王子的尾指緊緊勾著。

婚後，
王子要出征，
和公主勾手指尾，
承諾一定會回來。
可是十年來王子一直杳無音訊。
不少王子勸她改嫁，
公主要求誰能為她戴上適合她尾指的戒指，
便和那人結婚。

可是一直以來，
都沒有人做到，
直到有一天，
一個乞丐來到，
公主一視同仁給予他機會。
乞丐把尾指伸出來，
和公主的尾指緊勾著，
原來他就是失蹤多年的王子。
他們終於相逢，
可是第二天王子卻消失了。
原來王子已經死了，
他是為了實踐承諾，
所以化為鬼魂回來，
七七四十九天他便要走，
和公主重逢的那一天，
就是最後一天。

公主最後找到了王子的屍骨，
在他身旁自殺恂情。


２）勾手指尾的故事

A pinky promise (also known as a pinky swear) is made when a person wraps one of their pinky fingers around the other person's pinky and makes a promise.

On the 49th day after his disappearance, he came back, but only to realize he came back as a ghost. As the prince kept his promise, he after death.

In India, holding up the little finger is also a signal of "katti" or a broken friendship, a sign that someone is angry, or a playful suggestion that the person flashing the pinky is not going to speak to you.

In India, holding up the pinky is a signal that the person has to urinate.

Similarly, in Indonesia, when a man points his pinky finger downward it is a signal that he needs to urinate.
