    You probably know about Single's Day (Nov.11) in China, when people stay up very late at night to shop online in order to save a lot of money. Well, the US has something similar called Black Friday.

    Black Friday is the Friday after Thanksgiving. This year it fell on Nov.27. It's the start of the holiday shopping season and most people don't have to go to work that day. So people start to think about what gifts they want to buy for Christmas.

    The name Black Friday comes from ink. A long time ago, shops used ink for book keeping all their sales. So when there was a lot of black ink on the page that meant the business sold a lot.

While Single's Day is usually for online shopping, a lot of shopping on Black Friday is done at actual stores Shoppers look for deals especially on electronics like televisions, computers and video game systems. These things typically have high prices, but on this day, there are only a few available at the very low sale prices. So people sometimes fight over these things.

    Some people will wait in line for hours before midnight when stores finally open. People camp out in the cold and sometimes get hurt when the doors open and people rush in.

    But lately a few stores have been starting sales even earlier on Thanksgiving Day. Stores do this to hopefully get more shoppers and stay ahead of the competition.
