"光棍节"起源于打麻将？

An old story goes that once there were four single men, leading very boring lives. None of them were married, or had lovers, or did anything exciting. They just sat around all day and played Mahjong.
故事从四个过着单调生活的单身汉说起。他们没有人结婚，连女朋友都没有，日子过得无精打采，终日打麻将度过。

One day they played Mahjong from 11 in the morning until 11 at night. During the game, no matter who won, the winning card was always the "four columns" card (the card shows four independent, parallel columns in two lines). Even more of a coincidence, it was Nov 11, or 11/11. In order to commemorate the day, they nicknamed it Singles Day.
有一天他们打麻将从早上11点打到了晚上11点。奇妙的是，不管谁赢，都赢在了“四条”上。更加巧合的是，这一天正是11月11号。为了纪念这一天，他们给它命名为“光棍节”。

Singles Day was first celebrated at various universities in Nanjing, capital city of Jiangsu Province during the 1990s. It got the name Singles Day because the date is comprised of four "ones". These college students have since graduated, and carried their university tradition into society. Singles Day is now a special day for all fashionable youths.
光棍节最先在90年代的江苏南京各大高校兴起。之所以叫“光棍节”是因为这一天的日子有四个光棍一样的“1”。大学生们毕业了，把这个传统带到了社会上，光棍节就成了时尚青年们的一个特殊节日。

The main way to celebrate Singles Day is to have dinner with your single friends, but it's important that each person pay their own way to show their independence. People also hold "blind date" parties in an attempt to bid goodbye to their single lives.
主流的庆祝方式就是和光棍朋友们一起搓一顿，而且一定要实行AA制。为了脱离单身，人们也会举办相亲会，介绍单身男女认识。
