     Singles Day

     Singles Day falls on every November 11th and this new holiday is one only for people who are

still living the single life. I was a bit surprised when I googled "Singles Day" on the Internet, to find that

China is the only country in the world that has set a special day for singles to celebrate their lives.

To find out more about this celebration, read on.    

     Origin (起源) of Singles Day    

     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 (麻将).    

    One day they played Mahjong from 11 in the morning until 11 at night. Even more of a coincidence

(巧合), it was Nov.11, or 11/11 . In order to celebrate the day, they named it Singles Day.    

     University culture    

     Singles Day was first celebrated at various universities in Nanjing, capital city of Jiangsu Province

during the l990s. It got the name Singles Day because the date is comprised (包含) of four "ones".

These college students graduated and carried their university tradition into society.Singles Day is now

a special day for all fashionable youths.    

     The main way to celebrate Singles Day is to have dinner with your single friends, but it's important

that each person pays their own way to show their independence. People also hold "blinddate" (相亲)

parties in an attempt to say goodbye to their single lives.
