Singles' Day or Guanggun Jie is a holiday popular among young Chinese people that celebrate their pride in being single.

“双十一”或者说“光棍节”，是中国的年青 人庆贺 独身只身 的节日。

 The date, November 11th (11/11), was chosen because the number "1" resembles an individual who is alone.

因为数字“1”长得像“光棍”，所以人们选择11.11这一天作为独身只身 人士的节日。

然而，马云活生生把“光棍节”酿成 了“剁手日”……

The holiday has become the largest offline and online shopping day in the world, with Alibaba shoppers exceeding 168.2 billion yuan (US$25.4 billion) in spending during the 2017 celebration.

2017年的双十一，阿里巴巴花费 额到达 1682亿，这个节日酿成 世界上最年夜 的线上线下购物日。

Black Friday is an informal name for the day following Thanksgiving Day in the United States, the fourth Thursday of November, which has been regarded as the beginning of the country's Christmas shopping season since 1952.

黑色礼拜 五指的是美国感恩节（十一月第四个礼拜 四）之后的那一天，从1952年开端 ，这一天被当做圣诞节购物狂欢季的开端 。

It is said that the phrase “Black Friday” is originated in Philadelphia. It was used to describe the heavy and disruptive pedestrian and vehicle traffic that would occur on the day after Thanksgiving.

据说，“黑色礼拜 五”一词来源 于美国费城，用来描写 感恩节事后 的周五拥挤凌乱 的交通。

As the phrase became more widespread, a popular explanation became that this day represented the point in the year when retailers begin to turn a profit, thus going from being "in the red" to being "in the black".

另一种说明 是，感恩节事后 的周五，商家由吃亏 变为盈利。

为什么盈利是“in the black”呢？

因为以前人们用钢笔写字记账，习惯上用黑色墨水记载 盈利的数字，红色墨水记载 吃亏 的数字。所以“black”代表“盈利”，“red”代表“赤字”。

“黑色礼拜 五”堪称美国的“双十一”！
