Because American shopping malls generally use red pens to record deficits and black pens to record profits, this Friday after Thanksgiving has greatly increased the profits of shopping malls, so it is called Black Friday by merchants. Merchants expect to get the biggest profit this year through Christmas shopping that started on this day.

Promotion: On Black Friday, most shops will open at five or six in the morning, and some even earlier. Merchants will also take measures such as advertising in newspapers a few days before Thanksgiving, issuing coupons, and drastically reducing commodity prices to attract customers. Many consumers regard this day as a golden moment to prepare Christmas presents or buy bargains.
Due to the limited quantity of goods with reduced prices, many popular shops would line up in front of the door the night before. At the moment when the store opens, there are occasional stampedes caused by overcrowding. Because the merchants didn't publish their list of goods at reduced prices until the last minute, and regarded it as a trade secret, the price reduction information obtained from various channels often appeared on the Internet a few weeks ago, thus causing some legal disputes.
